* getloadavg: clean out old Emacs and Autoconf cruftPaul Eggert2012-07-101-0/+2
| | | | | | | | See Glenn Morris in <http://bugs.gnu.org/11905>. * lib/getloadavg.c: Include <config.h>, <stdbool.h> always. Include <sys/param.h> if HAVE_SYS_PARAM_H, not if unix or __unix. (LDAV_CVT): Remove no-longer-used LOAD_AVE_CVT hook. * m4/getloadavg.m4 (gl_PREREQ_GETLOADAVG): Check for <sys/param.h>.
* getopt: Simplify after Emacs changed.Bruno Haible2012-07-091-11/+4
| | | | | * m4/getopt.m4 (gl_FUNC_GETOPT_POSIX): Inline gl_GETOPT_IFELSE. (gl_GETOPT_IFELSE): Remove macro.
* getloadavg, getopt: fix commentary re configure.inPaul Eggert2012-07-091-3/+0
| | | | | | | | | | Autoconf is deprecating the name 'configure.in', so change it to to the new name 'configure.ac' in a couple of places. * lib/getloadavg.c: configure.in -> configure.ac, in comment. * m4/getopt.m4 (gl_GETOPT_IFELSE, gl_GETOPT_SUBSTITUTE_HEADER) (gl_PREREQ_GETOPT): Remove obsolete commentary re Emacs configure.in. Emacs has renamed it to configure.ac, and it no longer refers to these macros anyway.
* canonicalize[-lgpl]: handle "guessing" values when cross-buildingLudovic Courtès2012-07-081-8/+20
| | | | | | | * m4/canonicalize.m4 (gl_FUNC_CANONICALIZE_FILENAME_MODE) (gl_CANONICALIZE_LGPL): Check whether $gl_cv_func_realpath_works matches "*yes" instead of just "yes". Regression introduced in commit e0bcf6626cde8dad4bfbdc4045c744f0cd8b9e24.
* canonicalize: make the right guess when cross-compiling to GNULudovic Courtès2012-07-081-5/+5
| | | | | | * m4/canonicalize.m4 (gl_FUNC_REALPATH_WORKS): Match also "gnu*" to determine whether cross-compiling to glibc systems, so as to include GNU/Hurd.
* sys_time: allow too-wide tv_secPaul Eggert2012-07-061-2/+6
| | | | | | | | | * m4/sys_time_h.m4 (gl_HEADER_SYS_TIME_H_BODY): Allow struct timeval even if tv_sec is wider than time_t. This allows OpenBSD 5.1 amd64 and fixes an Emacs porting glitch with utimens.c, as without this patch gnulib replaces struct timeval and OpenBSD futimes therefore has a type mismatch. * doc/posix-headers/sys_time.texi: Mention this.
* pthread: check for both pthread_create and pthread_joinPaul Eggert2012-07-051-7/+32
| | | | | | | | * m4/pthread.m4 (gl_PTHREAD_CHECK): Revert previous change, but alter the check so that it tests for both pthread_create and pthread_join. This should be more portable to hosts like OSF/1 5.1. Suggested by Bruno Haible and Richard Yao in <http://lists.gnu.org/archive/html/bug-gnulib/2012-07/msg00048.html>.
* pthread: check for pthread_create, not pthread_joinPaul Eggert2012-07-041-26/+7
| | | | | | | | * m4/pthread.m4 (gl_PTHREAD_CHECK): Check for pthread_create, not pthread_join. On FreeBSD 9, pthread_create is in libpthread but pthread_join in libc. I hope this removes the need for all the OSF/1 5.1 pthread_join business. Reported by Richard Yao in <http://lists.gnu.org/archive/html/bug-gnulib/2012-07/msg00042.html>.
* parse-datetime: fix failure to diagnose invalid inputJim Meyering2012-07-041-1/+2
| | | | | | | | | | | | date -d "$(printf '\xb0')" would print 00:00:00 with today's date rather than diagnosing the invalid input. Now it reports this: date: invalid date '\260' * lib/parse-datetime.y (to_uchar): Define. (yylex): Don't sign-extend "other" bytes. * m4/parse-datetime.m4: Require AC_C_INLINE for first use of "inline". Thanks to Bruno Haible for the patch to this file. * tests/test-parse-datetime.c (main): Add a test to trigger the bug. Peter Evans reported the bug in GNU date: http://bugs.gnu.org/11843
* fsusage: avoid needless check on GNU/LinuxPaul Eggert2012-07-021-26/+27
| | | | | * m4/fsusage.m4 (gl_FILE_SYSTEM_USAGE): Omit STAT_STATFS3_OSF1 check on GNU/Linux systems, since it can't possibly work.
* log10f: Fix possible configuration problem.Bruno Haible2012-06-281-2/+2
| | | | | | * m4/log10f.m4 (gl_FUNC_LOG10F): Augment LIBS by $LOG10F_LIBM, not $LOGF_LIBM. Reported by Carlos O'Donell <carlos_odonell@mentor.com>.
* remove: No longer override on all platforms. Fixes bug from 2012-03-20.Bruno Haible2012-06-281-2/+2
| | | | | | * m4/remove.m4 (gl_FUNC_REMOVE): Test gl_cv_func_unlink_honors_slashes, not gl_cv_func_unlink_works. Reported by Carlos O'Donell <carlos_odonell@mentor.com>.
* root-uid: new modulePaul Eggert2012-06-261-1/+8
| | | | | | | | | | | | | | | | | | | | | This is for portability to Tandem's NonStop Kernel. * lib/root-uid.h, modules/root-uid: New files. * lib/euidaccess.c, lib/pt_chown.c, lib/unlinkdir.c: * lib/write-any-file.c, tests/test-sethostname2.c: Include "root-uid.h". * lib/euidaccess.c (euidaccess): * lib/pt_chown.c (main): * lib/unlinkdir.c (cannot_unlink_dir): * lib/write-any-file.c (can_write_any_file): * m4/mknod.m4 (gl_FUNC_MKNOD): * tests/test-sethostname2.c (geteuid, main): Don't assume ROOT_UID == 0. * modules/euidaccess (Depends-on): * modules/pt_chown (Depends-on): * modules/sethostname-tests (Depends-on): * modules/unlinkdir (Depends-on): * modules/write-any-file (Depends-on): Add root-uid.
* getopt-posix: No longer guarantee that option processing is resettable.Bruno Haible2012-06-261-113/+108
| | | | | | | | | | * doc/posix-functions/getopt.texi: Drop description of problem with internal state. Fix info about mingw and msvc9. * m4/getopt.m4 (gl_GETOPT_CHECK_HEADERS): Don't require a resettable option processing by getopt(). Run three test programs instead of one. Simplify cross-compilation guess. * NEWS: Mention the change. Reported by Rich Felker <dalias@aerifal.cx>.
* ptsname_r: Fix test failures on IRIX, Solaris.Bruno Haible2012-06-241-2/+35
| | | | | | | | | | * m4/ptsname_r.m4 (gl_PREREQ_PTSNAME_R): Test whether isatty sets errno when it fails. Define ISATTY_FAILS_WITHOUT_SETTING_ERRNO accordingly. * lib/ptsname_r.c: Include <fcntl.h>. (__ptsname_r): When isatty returned false, then on IRIX, Solaris set errno if fd is invalid. * tests/test-isatty.c (main): Update comments.
* time: fix obsolete commentPaul Eggert2012-06-231-2/+2
| | | | | * m4/time_h.m4 (gl_CHECK_TYPE_STRUCT_TIMESPEC): Remove obsolete reference to HAVE_STRUCT_TIMESPEC in comment.
* getopt-gnu: Handle suboptimal getopt_long's abbreviation handling.Bruno Haible2012-06-231-1/+43
| | | | | | | * m4/getopt.m4 (gl_GETOPT_CHECK_HEADERS): If getopt_long exists but does not handle abbreviated long options with equivalent disambiguations, set gl_replace_getopt to yes. * doc/posix-functions/getopt.texi: Mention the OpenBSD 5.0 problem.
* time_r: fix typo that always overrode localtime_r declPaul Eggert2012-06-221-1/+1
| | | | | | * m4/time_r.m4 (gl_TIME_R): Use AC_CHECK_DECLS, not AC_CHECK_DECLS_ONCE, since localtime_r is declared in <time.h>, not in a standard include.
* Write "Mac OS X" instead of "MacOS X".Bruno Haible2012-06-2252-167/+167

(statvfs_works): New function, for dynamically testing statvfs. (get_fs_usage) [STAT_STATVFS]: Use it. * m4/fsusage.m4 (gl_FILE_SYSTEM_USAGE): Remove static check for statvfs on GNU/Linux hosts, since it's now done dynamically.

* unistd_h: make it easier to avoid sys_types_hPaul Eggert2012-05-043-10/+22
| | | | | | | | | | | | | This is useful for Emacs, which has its own method of porting to Windows, and which therefore does not need the sys_types_h module. * m4/off_t.m4: New file, defining gl_TYPE_OFF_T, which contains code moved here from gl_SYS_TYPES_H. * m4/sys_types_h.m4 (gl_SYS_TYPES_H): Require it instead of using the code directly. * m4/unistd_h.m4 (gl_UNISTD_H): Require gl_TYPE_OFF_T, not gl_SYS_TYPES_H. * modules/sys_types (Files): * modules/unistd (Files): Add m4/off_t.m4.
* lstat: Avoid "guessing no" when cross-compiling to glibc systems.Bruno Haible2012-05-044-27/+37
| | | | | | | | | | * m4/lstat.m4 (gl_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): When cross- compiling, set gl_cv_func_lstat_dereferences_slashed_symlink to "guessing yes" or "guessing no". (gl_FUNC_LSTAT): Update. * m4/fstatat.m4 (gl_FUNC_FSTATAT): Update. * m4/openat.m4 (gl_FUNC_OPENAT): Update. * m4/unlinkat.m4 (gl_FUNC_UNLINKAT): Update.
* *alloc-gnu, eealloc: Avoid "guessing no" when cross-compiling to glibc.Bruno Haible2012-05-043-5/+95
| | | | | | | | * m4/malloc.m4 (_AC_FUNC_MALLOC_IF): Override in autoconf < 2.70. * m4/realloc.m4 (_AC_FUNC_REALLOC_IF): Override in autoconf < 2.70. * m4/calloc.m4 (_AC_FUNC_CALLOC_IF): Require AC_CANONICAL_HOST. When cross-compiling, choose the first alternative on glibc systems. * modules/eealloc (Files): Add m4/malloc.m4, m4/realloc.m4.
* getgroups: Avoid "guessing no" when cross-compiling to glibc systems.Bruno Haible2012-05-041-28/+87
| | | | | * m4/getgroups.m4 (AC_FUNC_GETGROUPS): Override in autoconf < 2.70. (gl_FUNC_GETGROUPS): Adapt to change of ac_cv_func_getgroups_works.
