+/* The i386 floating point hardware (the 387 compatible FPU, not the modern
+ SSE/SSE2 hardware) has a controllable rounding precision. It is specified
+ through the 'PC' bits in the FPU control word ('fctrl' register). (See
+ the GNU libc i386 <fpu_control.h> header for details.)
+
+ On some platforms, such as Linux or Solaris, the default precision setting
+ is set to "extended precision". This means that 'long double' instructions
+ operate correctly, but 'double' computations often produce slightly
+ different results as on strictly IEEE 754 conforming systems.
+
+ On some platforms, such as NetBSD, the default precision is set to
+ "double precision". This means that 'long double' instructions will operate
+ only as 'double', i.e. lead to wrong results. Similarly on FreeBSD 6.4, at
+ least for the division of 'long double' numbers.
+
+ The FPU control word is under control of the application, i.e. it is
+ not required to be set either way by the ABI. (In fact, the i386 ABI
+ https://www.linux-mips.org/pub/linux/mips/doc/ABI/abi386-4.pdf page 3-12 = page 38
+ is not clear about it. But in any case, gcc treats the control word
+ like a "preserved" register: it emits code that assumes that the control
+ word is preserved across calls, and it restores the control word at the
+ end of functions that modify it.)
+
+ See Vincent Lefèvre's page https://www.vinc17.net/research/extended.en.html
+ for a good explanation.
+ See http://www.uwsg.iu.edu/hypermail/linux/kernel/0103.0/0453.html for

+ given in OPTSTRING.
+
+ If an element of ARGV starts with '-', and is not exactly "-" or "--",
+ then it is an option element. The characters of this element
+ (aside from the initial '-') are option characters. If 'getopt'
+ is called repeatedly, it returns successively each of the option characters
+ from each of the option elements.
+
+ If 'getopt' finds another option character, it returns that character,
+ updating 'optind' and 'nextchar' so that the next call to 'getopt' can
+ resume the scan with the following option character or ARGV-element.
+
+ If there are no more option characters, 'getopt' returns -1.
+ Then 'optind' is the index in ARGV of the first ARGV-element
+ that is not an option. (The ARGV-elements have been permuted
+ so that those that are not options now come last.)
+
+ OPTSTRING is a string containing the legitimate option characters.
+ If an option character is seen that is not listed in OPTSTRING,
+ return '?' after printing an error message. If you set 'opterr' to
+ zero, the error message is suppressed but we still return '?'.
+
+ If a char in OPTSTRING is followed by a colon, that means it wants an arg,
+ so the following text in the same ARGV-element, or the text of the following
+ ARGV-element, is returned in 'optarg'. Two colons mean an option that
+ wants an optional arg; if there is text in the current ARGV-element,
+ it is returned in 'optarg', otherwise 'optarg' is set to zero.
+
+ If OPTSTRING starts with '-' or '+', it requests different methods of
+ handling the non-option ARGV-elements.
+ See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above.
+
+ Long-named options begin with '--' instead of '-'.
+ Their names may be abbreviated as long as the abbreviation is unique
+ or is an exact match for some defined option. If they have an
+ argument, it follows the option name in the same ARGV-element, separated
+ from the option name by a '=', or else the in next ARGV-element.
+ When 'getopt' finds a long-named option, it returns 0 if that option's
+ 'flag' field is nonzero, the value of the option's 'val' field
+ if the 'flag' field is zero.
+
+ The elements of ARGV aren't really const, because we permute them.
+ But we pretend they're const in the prototype to be compatible
+ with other systems.
+
+ LONGOPTS is a vector of 'struct option' terminated by an
+ element containing a name which is zero.
+
+ LONGIND returns the index in LONGOPT of the long-named option found.
+ It is only valid when a long-named option has been found by the most
+ recent call.
+
+ If LONG_ONLY is nonzero, '-' as well as '--' can introduce
+ long-named options. */

+ - If a byte of longword1 is zero, step 1 and 2 transform it into 0xff,
+ and step 3 transforms it into 0x80. A carry can also be propagated
+ to more significant bytes.
+ - If a byte of longword1 is nonzero, let its lowest 1 bit be at
+ position k (0 <= k <= 7); so the lowest k bits are 0. After step 1,
+ the byte ends in a single bit of value 0 and k bits of value 1.
+ After step 2, the result is just k bits of value 1: 2^k - 1. After
+ step 3, the result is 0. And no carry is produced.
+ So, if longword1 has only non-zero bytes, tmp is zero.
+ Whereas if longword1 has a zero byte, call j the position of the least
+ significant zero byte. Then the result has a zero at positions 0, ...,
+ j-1 and a 0x80 at position j. We cannot predict the result at the more
+ significant bytes (positions j+1..3), but it does not matter since we
+ already have a non-zero bit at position 8*j+7.

+ 2. & ~longword1.
+ 3. & a mask consisting of 0x80 in every byte.
+ Consider what happens in each byte:
+ - If a byte of longword1 is zero, step 1 and 2 transform it into 0xff,
+ and step 3 transforms it into 0x80. A carry can also be propagated
+ to more significant bytes.
+ - If a byte of longword1 is nonzero, let its lowest 1 bit be at
+ position k (0 <= k <= 7); so the lowest k bits are 0. After step 1,
+ the byte ends in a single bit of value 0 and k bits of value 1.
+ After step 2, the result is just k bits of value 1: 2^k - 1. After
+ step 3, the result is 0. And no carry is produced.
+ So, if longword1 has only non-zero bytes, tmp is zero.
+ Whereas if longword1 has a zero byte, call j the position of the least
+ significant zero byte. Then the result has a zero at positions 0, ...,
+ j-1 and a 0x80 at position j. We cannot predict the result at the more
+ significant bytes (positions j+1..3), but it does not matter since we
+ already have a non-zero bit at position 8*j+7.
+
+ So, the test whether any byte in longword1 is zero is equivalent to

+ Programs that use <stdbool.h> should be aware of some limitations
+ and standards compliance issues.
+
+ Standards compliance:
+
+ - <stdbool.h> must be #included before 'bool', 'false', 'true'
+ can be used.
+
+ - You cannot assume that sizeof (bool) == 1.
+
+ - Programs should not undefine the macros bool, true, and false,
+ as C99 lists that as an "obsolescent feature".
+
+ Limitations of this substitute, when used in a C89 environment:
+
+ - <stdbool.h> must be #included before the '_Bool' type can be used.
+
+ - You cannot assume that _Bool is a typedef; it might be a macro.
+
+ - Bit-fields of type 'bool' are not supported. Portable code
+ should use 'unsigned int foo : 1;' rather than 'bool foo : 1;'.
+
+ - In C99, casts and automatic conversions to '_Bool' or 'bool' are
+ performed in such a way that every nonzero value gets converted
+ to 'true', and zero gets converted to 'false'. This doesn't work
+ with this substitute. With this substitute, only the values 0 and 1
+ give the expected result when converted to _Bool' or 'bool'.
+
+ - C99 allows the use of (_Bool)0.0 in constant expressions, but
+ this substitute cannot always provide this property.
+
+ Also, it is suggested that programs use 'bool' rather than '_Bool';
+ this isn't required, but 'bool' is more common. */

+/* Set up the following warnings, based on which modules are in use.
+ GNU Coding Standards discourage the use of fseek, since it imposes
+ an arbitrary limitation on some 32-bit hosts. Remember that the
+ fseek module depends on the fseeko module, so we only have three
+ cases to consider:
+
+ 1. The developer is not using either module. Issue a warning under
+ GNULIB_POSIXCHECK for both functions, to remind them that both
+ functions have bugs on some systems. _GL_NO_LARGE_FILES has no
+ impact on this warning.
+
+ 2. The developer is using both modules. They may be unaware of the
+ arbitrary limitations of fseek, so issue a warning under
+ GNULIB_POSIXCHECK. On the other hand, they may be using both
+ modules intentionally, so the developer can define
+ _GL_NO_LARGE_FILES in the compilation units where the use of fseek
+ is safe, to silence the warning.
+
+ 3. The developer is using the fseeko module, but not fseek. Gnulib
+ guarantees that fseek will still work around platform bugs in that
+ case, but we presume that the developer is aware of the pitfalls of
+ fseek and was trying to avoid it, so issue a warning even when
+ GNULIB_POSIXCHECK is undefined. Again, _GL_NO_LARGE_FILES can be
+ defined to silence the warning in particular compilation units.
+ In C++ compilations with GNULIB_NAMESPACE, in order to avoid that
+ fseek gets defined as a macro, it is recommended that the developer
+ uses the fseek module, even if he is not calling the fseek function.
+
+ Most gnulib clients that perform stream operations should fall into
+ category 3. */

+ FCHAR_T The element type of the format string.
+ DCHAR_T The element type of the destination (result) string.
+ FCHAR_T_ONLY_ASCII Set to 1 to enable verification that all characters
+ in the format string are ASCII. MUST be set if
+ FCHAR_T and DCHAR_T are not the same type.
+ DIRECTIVE Structure denoting a format directive.
+ Depends on FCHAR_T.
+ DIRECTIVES Structure denoting the set of format directives of a
+ format string. Depends on FCHAR_T.
+ PRINTF_PARSE Function that parses a format string.
+ Depends on FCHAR_T.
+ DCHAR_CPY memcpy like function for DCHAR_T[] arrays.
+ DCHAR_SET memset like function for DCHAR_T[] arrays.
+ DCHAR_MBSNLEN mbsnlen like function for DCHAR_T[] arrays.
+ SNPRINTF The system's snprintf (or similar) function.
+ This may be either snprintf or swprintf.
+ TCHAR_T The element type of the argument and result string
+ of the said SNPRINTF function. This may be either
+ char or wchar_t. The code exploits that

+/* Each of these macros verifies that its argument R is nonzero. To

+ assert (R), there is no run-time overhead.
+
+ If _Static_assert works, verify (R) uses it directly. Similarly,
+ _GL_VERIFY_TRUE works by packaging a _Static_assert inside a struct
+ that is an operand of sizeof.
+
+ The code below uses several ideas for C++ compilers, and for C
+ compilers that do not support _Static_assert:
+
+ * The first step is ((R) ? 1 : -1). Given an expression R, of
+ integral or boolean or floating-point type, this yields an
+ expression of integral type, whose value is later verified to be
+ constant and nonnegative.
+
+ * Next this expression W is wrapped in a type
+ struct _gl_verify_type {
+ unsigned int _gl_verify_error_if_negative: W;
+ }.
+ If W is negative, this yields a compile-time error. No compiler can
+ deal with a bit-field of negative size.
+
+ One might think that an array size check would have the same
+ effect, that is, that the type struct { unsigned int dummy[W]; }
+ would work as well. However, inside a function, some compilers
+ (such as C++ compilers and GNU C) allow local parameters and
+ variables inside array size expressions. With these compilers,
+ an array size check would not properly diagnose this misuse of
+ the verify macro:
+
+ void function (int n) { verify (n < 0); }
+
+ * For the verify macro, the struct _gl_verify_type will need to
+ somehow be embedded into a declaration. To be portable, this
+ declaration must declare an object, a constant, a function, or a
+ typedef name. If the declared entity uses the type directly,
+ such as in
+
+ struct dummy {...};
+ typedef struct {...} dummy;
+ extern struct {...} *dummy;
+ extern void dummy (struct {...} *);
+ extern struct {...} *dummy (void);
+
+ two uses of the verify macro would yield colliding declarations
+ if the entity names are not disambiguated. A workaround is to
+ attach the current line number to the entity name:
+
+ #define _GL_CONCAT0(x, y) x##y
+ #define _GL_CONCAT(x, y) _GL_CONCAT0 (x, y)
+ extern struct {...} * _GL_CONCAT (dummy, __LINE__);
+
+ But this has the problem that two invocations of verify from
+ within the same macro would collide, since the __LINE__ value
+ would be the same for both invocations. (The GCC __COUNTER__
+ macro solves this problem, but is not portable.)
+
+ A solution is to use the sizeof operator. It yields a number,
+ getting rid of the identity of the type. Declarations like
+
+ extern int dummy [sizeof (struct {...})];
+ extern void dummy (int [sizeof (struct {...})]);
+ extern int (*dummy (void)) [sizeof (struct {...})];
+
+ can be repeated.
+
+ * Should the implementation use a named struct or an unnamed struct?
+ Which of the following alternatives can be used?
+
+ extern int dummy [sizeof (struct {...})];
+ extern int dummy [sizeof (struct _gl_verify_type {...})];
+ extern void dummy (int [sizeof (struct {...})]);
+ extern void dummy (int [sizeof (struct _gl_verify_type {...})]);
+ extern int (*dummy (void)) [sizeof (struct {...})];
+ extern int (*dummy (void)) [sizeof (struct _gl_verify_type {...})];
+
+ In the second and sixth case, the struct type is exported to the
+ outer scope; two such declarations therefore collide. GCC warns
+ about the first, third, and fourth cases. So the only remaining
+ possibility is the fifth case:
+
+ extern int (*dummy (void)) [sizeof (struct {...})];
+
+ * GCC warns about duplicate declarations of the dummy function if
+ -Wredundant-decls is used. GCC 4.3 and later have a builtin
+ __COUNTER__ macro that can let us generate unique identifiers for
+ each dummy function, to suppress this warning.
+
+ * This implementation exploits the fact that older versions of GCC,
+ which do not support _Static_assert, also do not warn about the
+ last declaration mentioned above.
+
+ * GCC warns if -Wnested-externs is enabled and verify() is used
+ within a function body; but inside a function, you can always
+ arrange to use verify_expr() instead.
+
+ * In C++, any struct definition inside sizeof is invalid.
+ Use a template type to work around the problem. */

+/* _GL_WARN_ON_USE (function, "literal string") issues a declaration
+ for FUNCTION which will then trigger a compiler warning containing
+ the text of "literal string" anywhere that function is called, if
+ supported by the compiler. If the compiler does not support this
+ feature, the macro expands to an unused extern declaration.
+
+ _GL_WARN_ON_USE_ATTRIBUTE ("literal string") expands to the
+ attribute used in _GL_WARN_ON_USE. If the compiler does not support
+ this feature, it expands to empty.
+
+ These macros are useful for marking a function as a potential
+ portability trap, with the intent that "literal string" include
+ instructions on the replacement function that should be used
+ instead.
+ _GL_WARN_ON_USE is for functions with 'extern' linkage.
+ _GL_WARN_ON_USE_ATTRIBUTE is for functions with 'static' or 'inline'
+ linkage.
+
+ However, one of the reasons that a function is a portability trap is
+ if it has the wrong signature. Declaring FUNCTION with a different
+ signature in C is a compilation error, so this macro must use the
+ same type as any existing declaration so that programs that avoid
+ the problematic FUNCTION do not fail to compile merely because they
+ included a header that poisoned the function. But this implies that
+ _GL_WARN_ON_USE is only safe to use if FUNCTION is known to already
+ have a declaration. Use of this macro implies that there must not
+ be any other macro hiding the declaration of FUNCTION; but
+ undefining FUNCTION first is part of the poisoning process anyway
+ (although for symbols that are provided only via a macro, the result
+ is a compilation error rather than a warning containing
+ "literal string"). Also note that in C++, it is only safe to use if
+ FUNCTION has no overloads.
+
+ For an example, it is possible to poison 'getline' by:
+ - adding a call to gl_WARN_ON_USE_PREPARE([[#include <stdio.h>]],

+# Find the absolute name of a header file, testing first if the header exists.
+# If the header were sys/inttypes.h, this macro would define
+# ABSOLUTE_SYS_INTTYPES_H to the '""' quoted absolute name of sys/inttypes.h
+# in config.h
+# (e.g. '#define ABSOLUTE_SYS_INTTYPES_H "///usr/include/sys/inttypes.h"').
+# The three "///" are to pacify Sun C 5.8, which otherwise would say
+# "warning: #include of /usr/include/... may be non-portable".
+# Use '""', not '<>', so that the /// cannot be confused with a C99 comment.
+# Note: This macro assumes that the header file is not empty after
+# preprocessing, i.e. it does not only define preprocessor macros but also
+# provides some type/enum definitions or function/variable declarations.

+ Suppress extern inline with HP-UX cc, as it appears to be broken; see

+
+ Suppress extern inline with Sun C in standards-conformance mode, as it
+ mishandles inline functions that call each other. E.g., for 'inline void f
+ (void) { } inline void g (void) { f (); }', c99 incorrectly complains
+ 'reference to static identifier "f" in extern inline function'.
+ This bug was observed with Sun C 5.12 SunOS_i386 2011/11/16.
+
+ Suppress extern inline (with or without __attribute__ ((__gnu_inline__)))
+ on configurations that mistakenly use 'static inline' to implement
+ functions or macros in standard C headers like <ctype.h>. For example,
+ if isdigit is mistakenly implemented via a static inline function,
+ a program containing an extern inline function that calls isdigit
+ may not work since the C standard prohibits extern inline functions
+ from calling static functions (ISO C 99 section 6.7.4.(3).
+ This bug is known to occur on:
+
+ OS X 10.8 and earlier; see:
+ https://lists.gnu.org/r/bug-gnulib/2012-12/msg00023.html
+
+ DragonFly; see
+ http://muscles.dragonflybsd.org/bulk/bleeding-edge-potential/latest-per-pkg/ah-tty-0.3.12.log
+
+ FreeBSD; see:
+ https://lists.gnu.org/r/bug-gnulib/2014-07/msg00104.html
+
+ OS X 10.9 has a macro __header_inline indicating the bug is fixed for C and
+ for clang but remains for g++; see <https://trac.macports.org/ticket/41033>.
+ Assume DragonFly and FreeBSD will be similar.
+
+ GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99
+ inline semantics, unless -fgnu89-inline is used. It defines a macro
+ __GNUC_STDC_INLINE__ to indicate this situation or a macro
+ __GNUC_GNU_INLINE__ to indicate the opposite situation.
+ GCC 4.2 with -std=c99 or -std=gnu99 implements the GNU C inline
+ semantics but warns, unless -fgnu89-inline is used:

+dnl Sets INCLUDE_NEXT, INCLUDE_NEXT_AS_FIRST_DIRECTIVE, PRAGMA_SYSTEM_HEADER,

+dnl
+dnl INCLUDE_NEXT expands to 'include_next' if the compiler supports it, or to
+dnl 'include' otherwise.
+dnl
+dnl INCLUDE_NEXT_AS_FIRST_DIRECTIVE expands to 'include_next' if the compiler
+dnl supports it in the special case that it is the first include directive in
+dnl the given file, or to 'include' otherwise.
+dnl
+dnl PRAGMA_SYSTEM_HEADER can be used in files that contain #include_next,
+dnl so as to avoid GCC warnings when the gcc option -pedantic is used.
+dnl '#pragma GCC system_header' has the same effect as if the file was found
+dnl through the include search path specified with '-isystem' options (as
+dnl opposed to the search path specified with '-I' options). Namely, gcc
+dnl does not warn about some things, and on some systems (Solaris and Interix)
+dnl __STDC__ evaluates to 0 instead of to 1. The latter is an undesired side
+dnl effect; we are therefore careful to use 'defined __STDC__' or '1' instead
+dnl of plain '__STDC__'.
+dnl
+dnl PRAGMA_COLUMNS can be used in files that override system header files, so
+dnl as to avoid compilation errors on HP NonStop systems when the gnulib file
+dnl is included by a system header file that does a "#pragma COLUMNS 80" (which
+dnl has the effect of truncating the lines of that file and all files that it
+dnl includes to 80 columns) and the gnulib file has lines longer than 80

+#
+# The trouble is, aclocal is a bit thick. It'll see the old AC_DEFUN

+# using a macro with the same name in our local m4/libtool.m4 it'll
+# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
+# and doesn't know about Autoconf macros at all.)

+# included after everything else. This provides aclocal with the
+# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
+# because those macros already exist, or will be overwritten later.
+# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
+#
+# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
