URL: https://svn.lrde.epita.fr/svn/argp/trunk ChangeLog: 2007-02-02 SIGOURE Benoit <tsuna@lrde.epita.fr> Update to argp-1.4. * bootstrap: New. * build-aux: New. * strcasecmp.c: New. * vsnprintf.c: New. * argp-fs-xinl.c: Remove. * argp-xinl.c: Remove. * ChangeLog, * Makefile.am, * argp-ba.c, * argp-eexst.c, * argp-fmtstream.c, * argp-fmtstream.h, * argp-help.c, * argp-namefrob.h, * argp-parse.c, * argp-pv.c, * argp-pvh.c, * argp-test.c, * argp.h, * configure.ac: Update to 1.4. The following changes have been imported: 2004-03-02 Niels Möller <nisse@lysator.liu.se> * Makefile.am (EXTRA_DIST): Added strcasecmp.c. * argp-help.c: Declare strcasecmp. * strcasecmp.c (strcasecmp): New file. * argp-parse.c, argp-help.c: Conditionally include malloc.h. 2004-03-01 Niels Möller <nisse@lysator.liu.se> * argp-fmtstream.h [!HAVE_UNISTD_H]: Define ssize_t as int. * Makefile.am (EXTRA_PROGRAMS): Don't build argp-test, as it's the only program depending on the functions asprintf/vsnprintf. * configure.ac: Check for sleep and getpid. * argp-parse.c: Make inclusion of unistd.h conditional. (OPT_HANG): Recognize this option only if getpid and sleep are available. * argp-fmtstream.h: Make inclusion of unistd.h conditional. It's needed for ssize_t, at least on freebsd. 2004-03-01 Niels Möller <niels@s3.kth.se> * argp-eexst.c [!HAVE_SYSEXITS_H]: Hardcode EX_USAGE = 64. * configure.ac: Check for sysexits.h. trunk/Makefile.am | 3 trunk/argp-ba.c | 6 trunk/argp-eexst.c | 10 trunk/argp-fmtstream.c | 6 trunk/argp-fmtstream.h | 14 trunk/argp-help.c | 16 trunk/argp-namefrob.h | 6 trunk/argp-parse.c | 19 - trunk/argp-pv.c | 6 trunk/argp-pvh.c | 6 trunk/argp-test.c | 6 trunk/argp.h | 6 trunk/bootstrap | 3 trunk/configure.ac | 14 trunk/strcasecmp.c | 28 + trunk/vsnprintf.c | 833 +++++++++++++++++++++++++++++++++++++++++++++++++ 16 files changed, 938 insertions(+), 44 deletions(-) Index: trunk/argp.h =================================================================== --- trunk/argp.h (revision 2) +++ trunk/argp.h (revision 3) @@ -1,5 +1,5 @@ /* Hierarchial argument parsing. - Copyright (C) 1995, 96, 97, 98, 99, 2003, 2005 Free Software Foundation, Inc. + Copyright (C) 96, 97, 98, 99, 1995, 2003, 2005, 2007 Free Software Foundation, Inc.
