* getopt: port recent getopt changes to macOSPaul Eggert2017-04-091-0/+2
| | | | | | | | | | | | | | | Problem reported by Harald Maier (Bug#26398). The macOS C compiler uses __nonnull for its own purposes and that clashes with glibc's __nonnull. * lib/getopt.in.h: Add comment for _GL_ARG_NONNULL snippet. * lib/getopt_cdefs.in.h (__nonnull): Remove. * lib/getopt_core.h (getopt): * lib/getopt_ext.h (getopt_long, getopt_long_only): Use _GL_ARG_NONNULL, not __nonnull. * lib/unistd.in.h: Move snippet hooks to before where the getopt .h files are included, so that _GL_ARG_NONNULL is defined in time. * modules/getopt-posix (Depends-on): Add snippet/arg-nonnull. (getopt.h): Interpolate _GL_ARG_NONNULL snippet.
* getopt: split up getopt.in.h and eliminate __need_getoptZack Weinberg2017-04-061-248/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Over in glibc, all of the __need macros are being phased out in favor of small headers that declare only the necessary components, as this is much simpler and less prone to bugs. As getopt is shared with glibc, gnulib needs to do the same for __need_getopt. __need_getopt is misnamed; what it really means is "we want only the getopt features specified in POSIX, not the GNU extensions". glibc placed the "meat" of getopt.h into getopt_core.h and getopt_ext.h; these files can be shared verbatim with gnulib. The portability wrapper, on the other hand, they have renounced altogether; glibc's getopt.h will no longer be shared with gnulib at all. In exchange, certain glibc-specific quirks (having to do with __posix_getopt) no longer need appear in gnulib's headers at all. This patch merges getopt_core.h and getopt_ext.h from glibc, and splits up the current gnulib-side portability wrapper into three additional headers: getopt_pfx_core.h and getopt_pfx_ext.h handle __GETOPT_PREFIX for their respective headers, getopt_cdefs.in.h handles things like __BEGIN_DECLS and __THROW, and getopt.in.h and unistd.in.h just use them. All new files are clearly marked with whether they are shared with glibc. * lib/getopt.in.h: Eliminate __need_getopt. Break up into ... * lib/getopt_core.h, lib/getopt_ext.h: ... these new files shared with glibc, and ... * lib/getopt_cdefs.in.h, lib/getopt_pfx_core.h * lib/getopt_pfx_ext.h: ... these new files not shared with glibc. * lib/unistd.in.h: Include getopt_cdefs.h and getopt_pfx_core.h, instead of defining __need_getopt and including the full getopt.h. * m4/getopt.m4 (gl_GETOPT_SUBSTITUTE_HEADER): Check for sys/cdefs.h. Define substitution variables GETOPT_CDEFS_H and HAVE_SYS_CDEFS_H. * modules/getopt-posix (Files): Add new headers and sort list. (Depends-on): No longer need snippet/arg-nonnull. (Makefile.am): Generate getopt_cdefs.h.
* getopt: merge from glibcPaul Eggert2017-03-221-11/+30
| | | | | | | | | | | | This does not change anything substantial; it merely simplifies hypothetical merges back to glibc. * lib/getopt.c, lib/getopt.in.h, lib/getopt1.c, lib/getopt_int.h: Change copyright notice to match what is in glibc. * lib/getopt.c: Reorder includes to match glibc. Remove uses of USE_IN_LIBIO. Remove 'register'. In __LIBC code, use __open_memstream rather than open_memstream and __glibc_likely instead of __builtin_expect. * lib/getopt.in.h (__posix_getopt) [!__GETOPT_PREFIX]: New decl.

* stdlib: port to Solaris 2.6Paul Eggert2013-01-091-0/+2
| | | | | | | | | | | | | | Also, the code worked on Solaris 7 through 9 only by accident. Problem reported by Tom G. Christensen in <http://lists.gnu.org/archive/html/bug-gnulib/2013-01/msg00059.html>. * lib/stdlib.in.h: If __need_system_stdlib_h is defined, simply include the system stdlib.h. * lib/getopt.in.h (__need_system_stdlib_h): * lib/pthread.in.h (__need_system_stdlib_h): * lib/unistd.in.h (__need_system_stdlib_h) [!__GLIBC__]: Define when including <stdlib.h>, to avoid problems at least for the pthread case on Solaris 2.6 and 7.
