* posix/regex_internal.h (re_sub_match_top_t): Remove unused member

	next_last_offset.
	(struct re_dfa_t): Remove unused member states_alloc.
	* posix/regcomp.c (init_dfa): Don't initialize unused members.

2005-08-25  Paul Eggert  <eggert@cs.ucla.edu>

	* posix/regexec.c (set_regs): Don't alloca with an unbounded size.

	alloca modernization/simplification for regex.
	* posix/regex.c: Remove portability cruft for alloca.  This no longer
	needs to be at the start of the file, and can be moved into
	regex_internal.h and simplified.
	* posix/regex_internal.h: Include <alloca.h>.
	(__libc_use_alloca) [!defined _LIBC]: New macro.
	* posix/regexec.c (build_trtable): Remove "#ifdef _LIBC",
	since the code now works outside glibc.

2005-09-06  Ulrich Drepper  <drepper@redhat.com>

	* include/regex.h: Remove use of _RE_ARGS.

2005-08-25  Paul Eggert  <eggert@cs.ucla.edu>

	* posix/regexec.c (find_recover_state): Change "err" to "*err".

2005-08-24  Paul Eggert  <eggert@cs.ucla.edu>

	* posix/regcomp.c (regerror): Pointer args are 'restrict',
	as per POSIX.
	* posix/regex.h (regerror): Likewise.
	* manual/pattern.texi (POSIX Regexp Compilation): Likewise.
	Similarly for regcomp and regexec.  Also, first 2 args of regexec
	and 2nd arg of regerror are const.

	* posix/regex.c: Do not include <sys/types.h>, as POSIX no longer
	requires this.  (The code never needed it.)

2005-08-20  Paul Eggert  <eggert@cs.ucla.edu>

	* posix/regexec.c (sift_states_bkref): re_node_set_insert returns
	int, not reg_errcode_t.

	* posix/regex_internal.c (calc_state_hash): Put 'inline' before type,
	since some broken compilers warn about it otherwise.

	* posix/regcomp.c (create_initial_state): Remove duplicate decl.

2005-08-20  Paul Eggert  <eggert@cs.ucla.edu>

	* posix/regex.h (_RE_ARGS): Remove.  No longer needed, since we assume
	C89 or better.  All uses removed.

2005-09-06  Ulrich Drepper  <drepper@redhat.com>

	* posix/regex.c: Prevent using C++ compilers.

2005-08-19  Paul Eggert  <eggert@cs.ucla.edu>

	* posix/regcomp.c (duplicate_node): Return new index, not an error
	code, and let the caller return REG_ESPACE if out of space.  This
	removes an uninitialied-variable warning with GCC 4.0.1, and also
	avoids taking the address of a local variable.  All callers
	changed.

2005-09-06  Ulrich Drepper  <drepper@redhat.com>

	* include/time.h (__strptime_internal): Rename parameter to avoid
	bogus compiler warning.

2005-08-19  Jim Meyering  <jim@meyering.net>

	* posix/regexec.c (proceed_next_node): Redo local variables to
	avoid GCC shadowing warnings.

2005-09-06  Ulrich Drepper  <drepper@redhat.com>

	* posix/regex_internal.c (re_acquire_state): Minor code rearrangement.
	(re_acquire_state_context): Likewise.

2005-08-19  Paul Eggert  <eggert@cs.ucla.edu>

	* posix/regex_internal.c (re_string_realloc_buffers):
	(re_node_set_insert, re_node_set_insert_last, re_dfa_add_node):
	Rename local variables to avoid GCC shadowing warnings.

2005-07-08  Eric Blake  <ebb9@byu.net>
            Paul Eggert  <eggert@cs.ucla.edu>

	* posix/regcomp.c (init_dfa): Store __btowc value in wint_t, not
	wchar_t.  Remove now-unnecessary cast.
	(build_range_exp): Likewise.
