+
+ On 64-bit hosts (where size_t is 64 bits and int is 32 bits), the
+ old glibc regex code mishandles strings longer than 2**31 bytes.
+ This patch fixes this when the regex code is used in gnulib
+ (i.e., outside glibc).
+
+ This patch should not affect the use of the regex code inside
+ glibc. No doubt this problem also needs to be handled for glibc
+ as well, but the result will be an incompatible change to the

+ can be the the subject for another patch.

+
+2005-08-26 Simon Josefsson <jas@extundo.com>
+
+ * getpass.c: Use _WIN32 instead of WIN32, suggested by Bruno
+ Haible <bruno@clisp.org>.
+
+2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
+
+ * regexec.c (set_regs): Don't alloca with an unbounded size.
+
+ alloca modernization/simplification for regex.
+ * 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: Include <alloca.h>.

+
+2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
+
+ Make regex safe for g++. This fixes one real bug (an "err"

+ * regex_internal.c (build_wcs_upper_buffer): Return reg_errcode_t,

+
+2005-08-24 Paul Eggert <eggert@cs.ucla.edu>
+
+ * regcomp.c (regerror): 2nd arg is 'restrict', as per POSIX.
+ * regex.h (regerror): Likewise.
+
+ * regex.c: Do not include <sys/types.h>, as POSIX no longer
+ requires this. (The code never needed it.)
+
+ * regcomp.c, regex_internal.c, regex_internal.h, regexec.c:
+ All uses of recently-renamed identifiers changed to use the new,
+ POSIX-compliant names. The code will build and run just fine
+ without these changes, but it's better to eat our own dog food
+ and use the standard-conforming names.
+
+ * regex.h: Fix a multitude of POSIX name space violations.
+ These changes have an effect only for programs that define
+ _POSIX_C_SOURCE, _POSIX_SOURCE, or _XOPEN_SOURCE; they
+ do not change anything for programs compiled in the normal way.
+ Also, there is no effect on the ABI.
+
+ (_REGEX_SOURCE): New macro.
+ Do not include <stddef.h> if _XOPEN_SOURCE and VMS are both
+ defined and _GNU_SOURCE is not; this fixes a name space violation.
+
+ Rename the following macros to obey POSIX requirements.
+ The old names are still visible as macros if _REGEX_SOURCE is defined.
+ (REG_BACKSLASH_ESCAPE_IN_LISTS): renamed from
+ RE_BACKSLASH_ESCAPE_IN_LISTS.

+ (REG_DEBUG): renamed from RE_DEBUG.
+ (REG_INVALID_INTERVAL_ORD): renamed from RE_INVALID_INTERVAL_ORD.
+ (REG_IGNORE_CASE): renamed from RE_ICASE. This renaming is a bit
+ unusual, since we can't clash with the POSIX REG_ICASE.
+ (REG_CARET_ANCHORS_HERE): renamed from RE_CARET_ANCHORS_HERE.
+ (REG_CONTEXT_INVALID_DUP): renamed from RE_CONTEXT_INVALID_DUP.
+ (REG_NO_SUB): renamed from RE_NO_SUB.
+ (REG_SYNTAX_EMACS): renamed from RE_SYNTAX_EMACS.

+ RE_SYNTAX_POSIX_MINIMAL_BASIC.
+ (REG_SYNTAX_POSIX_EXTENDED): renamed from RE_SYNTAX_POSIX_EXTENDED.
+ (REG_SYNTAX_POSIX_MINIMAL_EXTENDED): renamed from
+ RE_SYNTAX_POSIX_MINIMAL_EXTENDED.
+ (REG_DUP_MAX): renamed from RE_DUP_MAX. No need to undef it.
+ (REG_UNALLOCATED): Renamed from REGS_UNALLOCATED.
+ (REG_REALLOCATE): Renamed from REGS_REALLOCATE.
+ (REG_FIXED): Renamed from REGS_FIXED.
+ (REG_NREGS): Renamed from RE_NREGS.
+
+ (REG_ICASE, REG_NEWLINE, REG_NOSUB): Do not depend on the values
+ of other REG_* macros, since POSIX says the user is allowed to
+ #undef these macros selectively.
+
+ (reg_errcode_t): Update comment stating what other tables need
+ to be consistent.
+
+ Rename the following enum values to obey POSIX requirements.
+ The old names are still visible as macros.
+ (_REG_ENOSYS): Renamed from REG_ENOSYS. Define even if _XOPEN_SOURCE
+ is not defined, since GNU is supposed to be a superset of POSIX as
+ much as possible, and since we want reg_errcode_t to be a signed
+ type for implementation consistency.
+ (_REG_NOERROR): Renamed from REG_NOERROR.
+ (_REG_NOMATCH): Renamed from REG_NOMATCH.
+ (_REG_BADPAT): Renamed from REG_BADPAT.
+ (_REG_ECOLLATE): Renamed from REG_ECOLLATE.
+ (_REG_ECTYPE): Renamed from REG_ECTYPE.

+ (REG_EBRACE, REG_BADBR, REG_ERANGE, REG_ESPACE, REG_BADRPT, REG_EEND):
+ (REG_ESIZE, REG_ERPAREN): Now macros, not enum constants.
+
+ (_REG_RE_NAME, _REG_RM_NAME): New macros.
+ (REG_TRANSLATE_TYPE): Renamed from RE_TRANSLATE_TYPE. All uses
+ changed. But support the old name if the new one is not defined
+ and if _REGEX_SOURCE.
+
+ Change the following member names in struct re_pattern_buffer.
+ The old names are still supported if !_REGEX_SOURCE.
+ The new names are always supported, regardless of _REGEX_SOURCE.
+ (re_buffer): Renamed from buffer.
+ (re_allocated): Renamed from allocated.
+ (re_used): Renamed from used.
+ (re_syntax): Renamed from syntax.
+ (re_fastmap): Renamed from fastmap.

+ (re_not_eol): Renamed from not_eol.
+ (re_newline_anchor): Renamed from newline_anchor.
+
+ Change the following member names in struct re_registers.
+ The old names are still supported if !_REGEX_SOURCE.
+ The new names are always supported, regardless of _REGEX_SOURCE.
+ (rm_num_regs): Renamed from num_regs.
+ (rm_start): Renamed from start.
+ (rm_end): Renamed from end.
+
+ (re_set_syntax, re_compile_pattern, re_compile_fastmap):
+ (re_search, re_search_2, re_match, re_match_2, re_set_registers):
+ Prepend __ to parameter names.
