+2003-03-13  Niels Möller  <nisse@cuckoo.hack.org>
+
+	* Released argp-standalone-1.2.
+
+	* Updated copyright years.
+
+2003-03-03  Niels Möller  <nisse@cuckoo.hack.org>
+
+	* argp-fmtstream.h: Don't include config.h here, let the .c-files
+	do that. Deleted definition of PRINTF_STYLE, that's in config.h.
+	When defining or disabling i/o locking functions, use uppercase
+	macro names like PUTC_UNLOCKED. This avoids conflicts if the
+	underlying functions are really macros defined by stdio. For
+	example on freebsd. Updated the files using these functions.
+
+2003-03-02  Niels Möller  <nisse@cuckoo.hack.org>
+
+	* argp-help.c: Don't include malloc.h. If any system still needs
+	it, we need a configure test for it. 
+	(hol_entry_help): Don't use a non-constant initializer, as that's
+	a GNU C extension.
+
+2003-02-23  Niels Moller  <nisse@carduelis>
+
+	* configure.ac: Use LSH_GCC_ATTRIBUTES. Deleted the definition of
+	UNUSED from the files that used it, it's now in config.h.
+
+2003-02-16  Niels Möller  <nisse@cuckoo.hack.org>
+
+	* argp-fmtstream.h: When disabling fwrite_unlocked, #undef it first.
+
+	* testsuite/permute-test: diff -q is not portable.
+	Redirect to /dev/null instead.
+
+2003-02-12  Niels Möller  <niels@s3.kth.se>
+
+	* argp-fmtstream.h: When disabling putc_unlocked, #undef it first.
+
+2003-02-10  Niels Möller  <niels@s3.kth.se>
+
+	* configure.ac (ARGP_CHECK_FUNC): Use AS_VAR_GET. Use AH_TEMPLATE.
+
+2003-02-10  Niels Möller  <nisse@cuckoo.hack.org>
+
+	* configure.ac (ARGP_CHECK_FUNC): New macro. Use it to test for
+	putc_unlocked. 
+
+2003-02-05  Niels Möller  <nisse@lysator.liu.se>
+
+	* argp-parse.c (argp_default_options): Fixed initializer.
+	* argp-test.c (options): Likewise.
+
+	* testsuite/permute-test (die): Fixed sh-compatible function
+	definition. 
+
+	* testsuite/ex4.c: Don't use error.h and the error function.
+
+	* .bootstrap: New file.
+
+2003-02-05  Niels Möller  <niels@s3.kth.se>
+
+	* Makefile.am (all): Deleted the explicit all target.
+	(LIBOBJS): Added explicit substitution.
+
+	* testsuite/ex3.c, testsuite/ex4.c: Complete initializers, to
+	avoid warnings from gcc.
+
+	* configure.ac: Updated for current autoconf and automake.
+	Fixed AC_CONFIG_HEADER call.
+	Use AC_GNU_SOURCE.
+	Use AC_CHECK_DECLS to check for program_invocation_name and
+	program_invocation_short_name.
+	
+	* argp-test.c (sub_options): Complete initializer, to avoid
+	warnings from gcc.
+	(sub_argp): Likewise.
+	(options): Likewise.
+
+	* argp-parse.c (argp_default_parser):
+	HAVE_PROGRAM_INVOCATION_SHORT_NAME renamed to
+	HAVE_DECL_PROGRAM_INVOCATION_SHORT_NAME. 
+	(argp_default_options): Complete initializer, to avoid
+	warnings from gcc. 
+
+	* argp-help.c (uparam_names): Complete initializer, to avoid
+	warnings from gcc. 
+	(__argp_short_program_name): HAVE_PROGRAM_INVOCATION_NAME renamed
+	to HAVE_DECL_PROGRAM_INVOCATION_NAME. Similarly for
+	HAVE_PROGRAM_INVOCATION_SHORT_NAME. 
+
+	* acinclude.m4: Deleted file.
+
+2003-02-04  Niels Möller  <nisse@cuckoo.hack.org>
+
+	* configure.ac: Bumped version to standalone-1.2.
+
+	* argp-parse.c (parser_parse_next): Call exchange before
+	processing the final arguments. Fixes bug reported by Akim Demaille.
+
+	* Makefile.am (SUBDIRS): Added testsuite.
+
+	* configure.ac: Output testsuite/Makefile.
+
+	* testsuite/run-tests: Script copied from nettle.
+
+	* testsuite/permute-test: New testcase, exercising
+	argument option permuting.
+
+	* testsuite/ex1-test: New testcase.
+
+	* testsuite/ex1.c, testsuite/ex3.c,
+	testsuite/ex4.c:  Added glibc example programs.
+
+2002-07-18  Niels Möller  <niels@s3.kth.se>
+
+	* configure.ac: Don't use -ggdb3 with gcc-2.96.
+
+2002-05-06  Niels Möller  <niels@s3.kth.se>
+
+	* configure.ac: Use AH_TEMPLATE for
+	PROGRAM_INVOCATION_NAME and PROGRAM_INVOCATION_SHORT_NAME. The
+	third arg to AC_DEFINE_UNQUOTED seems not to work here. 
+
+2002-05-05  Niels Möller  <nisse@lysator.liu.se>
+
+	* acconfig.h: Deleted file.
+
+	* configure.ac: Pass no arguments to AM_INIT_AUTOMAKE.
+	Don't substitute LIBOBJS.
+
+	* acinclude.m4: Use the three-argument form of
+	AC_DEFINE_UNQUOTED. 
+
+	* configure.ac: Update for automake-1.6.
+	* configure.ac: Renamed file, used to be configure.in.
+

+
+2001-02-18  Niels Möller  <nisse@cuckoo.localdomain>
+
+	* argp-parse.c (argp_default_parser): Let OPT_HANG print
+	the process id to stderr.
+
+2001-01-15  Niels Möller  <nisse@ehand.com>
+
+	* argp.h: #define PRINTF_STYLE, and use it instead of
+	using __attribute__ directly.
+
+2001-01-07  Niels Möller  <nisse@cuckoo.localdomain>
+
+	* argp.h: Added _argp_short_program_name and
+	__argp_short_program_name.

+	argp_short_program_name. 
+	(parser_parse_next): Removed old permutation handling code. 
+
+2001-01-06  Niels Möller  <nisse@cuckoo.localdomain>
+
+	* argp-namefrob.h: Added _argp_short_program_name.
+
+2001-01-02  Niels Möller  <nisse@cuckoo.localdomain>
+
+	* argp-help.c (hol_entry_help): Avoid using a
+	non-constant struct initializer.
+	(UNUSED): Define as a macro expanding to __attribute__ ..., if
+	compiling with gcc.
+
+	* argp-fmtstream.h (PRINTF_STYLE): Define this macro,
+	to expand to __attribute__ ... if compiling with gcc.
+
+	* argp-fmtstream.c (__argp_fmtstream_write,
+	__argp_fmtstream_puts, __argp_fmtstream_putc): Duplicate the
+	inline definitions in argp-fmtstream.h, for compilers that don't
+	do inlining.
+
+2000-12-28  Niels Möller  <nisse@cuckoo.localdomain>
+
+	* argp-help.c (fill_in_uparams): Use unsigned char * for
+	VAR and ARG. Fixed calls of isalnum, isspace and friends, reported
+	by Kalle Olavi Niemitalo.
+	(canon_doc_option): Fixed calls of isalnum, isspace and friends,
+	reported by Kalle Olavi Niemitalo.
+	(hol_entry_cmp): Fixed calls of tolower, reported by Kalle Olavi
+	Niemitalo.
+
+2000-12-23  Niels Möller  <nisse@lysator.liu.se>
+
+	* acinclude.m4: New file. 
+	* acinclude.m4: Reverted the definition of AC_CHECK_VAR
+	to take includes as argument, and renamed it to ARGP_CHECK_VAR.

+
+	* Removed getopt.c, getopt.h and getopt1.c from the src/argp
+	directory. 
+
+	* argp-parse.c (match_option, ARGP_COMPLETE): #if:ed out
+	completion code for long options.
+
+2000-11-30  Niels Möller  <nisse@cuckoo.localdomain>

+2000-11-27  Niels Möller  <nisse@cuckoo.localdomain>
+
+	* argp-help.c (argp_doc): Use the name strndup, not
+	__strndup. That probably breaks glibc builds.

+
+	* Makefile.am: Use @LIBOBJS@ when building test program. 
+

+	LIBOBJS. Add -I$srcdir to CPPFLAGS.
+
+	* src/argp: Added getopt.h, getopt.c and getopt1.c, which are
+	needed for separate compilation of argp.
+
+2000-11-27  Niels Möller  <nisse@cuckoo.localdomain>
+
+	* Updated argp from glibc-2.2.

+     DOC      - A descriptive string about this program; if it contains a
+                 vertical tab character (\v), the part after it will be
+                 printed *following* the options
+
+   The function PARSER takes the following arguments:
+     KEY  - An integer specifying which option this is (taken
+             from the KEY field in each struct argp_option), or
+             a special key specifying something else; the only
+             special keys we use here are ARGP_KEY_ARG, meaning
+             a non-option argument, and ARGP_KEY_END, meaning
+             that all arguments have been parsed
+     ARG  - For an option KEY, the string value of its
+             argument, or NULL if it has none
+     STATE- A pointer to a struct argp_state, containing
+             various useful information about the parsing state; used here
+             are the INPUT field, which reflects the INPUT argument to
+             argp_parse, and the ARG_NUM field, which is the number of the
+             current non-option argument being parsed
+   It should return either 0, meaning success, ARGP_ERR_UNKNOWN, meaning the
+   given KEY wasn't recognized, or an errno value indicating some other
+   error.
+
+   Note that in this example, main uses a structure to communicate with the
+   parse_opt function, a pointer to which it passes in the INPUT argument to
+   argp_parse.  Of course, it's also possible to use global variables
+   instead, but this is somewhat more flexible.
+
+   The OPTIONS field contains a pointer to a vector of struct argp_option's;
+   that structure has the following fields (if you assign your option
+   structures using array initialization like this example, unspecified
+   fields will be defaulted to 0, and need not be specified):
+     NAME   - The name of this option's long option (may be zero)
+     KEY    - The KEY to pass to the PARSER function when parsing this option,
+               *and* the name of this option's short option, if it is a
+               printable ascii character
+     ARG    - The name of this option's argument, if any
+     FLAGS  - Flags describing this option; some of them are:
+                 OPTION_ARG_OPTIONAL - The argument to this option is optional
+                 OPTION_ALIAS        - This option is an alias for the
+                                        previous option
+                 OPTION_HIDDEN       - Don't show this option in -help output
+     DOC    - A documentation string for this option, shown in -help output
+
+   An options vector should be terminated by an option with all fields zero. */

+   string (in the variable DOC), which allows documentation both

+   convention, the documentation before the options is just a
+   short string saying what the program does, and that afterwards
+   is longer, describing the behavior in more detail.  All
+   documentation strings are automatically filled for output,
