WEOF. Thanks to Eli Zaretskii for pointing out the problem.
Mon Jun 20 20:22:26 2011 Pat Rankin <rankin@pactechdata.com>
* dfa.c (addtok_wc): enclose prototype within #if MBS_SUPPORT.
Fri Jun 17 11:09:22 2011 Arnold D. Robbins <arnold@skeeve.com>
* Release 3.1.86: Final beta test tar ball for 4.0.
Fri Jun 17 10:55:27 2011 Arnold D. Robbins <arnold@skeeve.com>
Implement Rational Range Interpretation (RRI) directly in code.
* regex.h [RE_RANGES_IGNORE_LOCALES]: Remove macro and its use.
* dfa.c (parse_bracket_exp): Remove use of RE_RANGES_IGNORE_LOCALES
and just do it in code.
(hard-locale.h): Remove include.
(hard_LC_COLLATE): Remove variable and its uses.
* re.c (resetup): Remove use of RE_RANGES_IGNORE_LOCALES.
* regcomp.c (build_range_exp): Remove use of RE_RANGES_IGNORE_LOCALES
and just do it in code. Remove cmp_buf array; it's no longer needed.
* Makefile.am (base_sources): Remove hard_locale.h and hard_locale.c.
* hard_locale.h, hard_locale.c: Removed from dist.
Sun Jun 12 23:43:06 2011 Arnold D. Robbins <arnold@skeeve.com>
* re.c (resetup): Always turn on RE_RANGES_IGNORE_LOCALES.
Add justifying comment with URLs for the relevant portions of
POSIX. Thanks to Paul Eggert for pointing out the happy change
to the rules and supplying the URLs.
Wed Jun 8 22:41:30 2011 Arnold D. Robbins <arnold@skeeve.com>
* regcomp.c (build_range_exp): Add check for RE_NO_EMPTY_RANGES
from GNULIB regcomp.c, courtesy of GNU grep.
Wed Jun 8 22:10:03 2011 Arnold D. Robbins <arnold@skeeve.com>
* dfa.c: Sync with GNU grep.
Sun Jun 5 21:49:30 2011 Arnold D. Robbins <arnold@skeeve.com>
* Release 3.1.85: Fourth beta test tar ball for 4.0.
Sun Jun 5 21:39:17 2011 Arnold D. Robbins <arnold@skeeve.com>
* field.c (fpat_parse_field): Bug fix. Thanks to
"Radoulov, Dimitre" <cichomitiko@gmail.com> for pointing
out the problem.
Fri Jun 3 10:39:17 2011 Arnold D. Robbins <arnold@skeeve.com>
* regcomp.c (build_range_exp): Make syntax the first argument,
for compatibility with gnulib version of the file.
Wed Jun 1 06:29:27 2011 Pat Rankin <rankin@pactechdata.com>
* re.c (check_bracket_exp): Fix typo.
Tue May 31 23:01:00 2011 John Haque <j.eh@mchsi.com>

as the name of a variable.
* awkgram.y (check_special): Rework so can be called from
arg_assign.
Tue May 31 22:23:41 2011 Arnold D. Robbins <arnold@skeeve.com>
In order to attain the goal of having ranges act like they are
always in the C locale, bit the bullet and did the work in
the regex and dfa engines. The pre-processing routine was not
handling too many cases that a full regexp parser would catch.
* regex.h [RE_RANGES_IGNORE_LOCALES]: New syntax bit.
(RE_SYNTAX_GNU_AWK): Use it.
* dfa.c (parse_bracket_exp): If the RE_RANGES_IGNORE_LOCALES
is set, ignore locales when building a range.
* re.c (expand_range): Remove function and declaration.
(add_char): Remove function and declaration.
(make_regexp): Remove use of expand_range.
(resetup): Add RE_RANGES_IGNORE_LOCALES if --traditional.
* regcomp.c (build_range_exp): Add syntax variable as last argument.
Add code to check for RE_RANGES_IGNORE_LOCALES and do the right thing.
Adjust all calls.
Sun May 29 22:48:41 2011 Arnold D. Robbins <arnold@skeeve.com>
* re.c (expand_range): Handle cases where expanded range
includes '\\' (and ']'). Thanks to Juergen Daubert <jue@jue.li>.
Fatal error if end point is below start point ([z-a]),
thanks to John Haque. Don't repeat the last character in
the expansion. Thanks to Arnold Robbins.
Fri May 27 10:01:17 2011 Arnold D. Robbins <arnold@skeeve.com>
* Release 3.1.84: Third beta test tar ball for 4.0.
Thu May 26 22:10:08 2011 Arnold D. Robbins <arnold@skeeve.com>
* field.c (get_field): Enhance logic for setting NF if we're
using FPAT to parse fields. Can end up with weird cases. Thanks
to Pat Rankin for pointing them out.
Mon May 23 22:06:13 2011 Arnold D. Robbins <arnold@skeeve.com>
* awkgram.y: Allow newline after comma in range patterns,
per POSIX. Thanks to discussion in comp.lang.awk. (!!!)
Mon May 23 22:02:46 2011 John Haque <j.eh@mchsi.com>
* ext.c (get_actual_argument): Change argument type from
Node_var_new to Node_var when used as a scalar.
Sun May 22 11:56:40 2011 Arnold D. Robbins <arnold@skeeve.com>

* field (get_field): Adjust test for at end of record to >=;
fpat_parse_field can go beyond when matching null regexps.
Thanks to Pat Rankin.
Fri May 20 11:00:17 2011 Arnold D. Robbins <arnold@skeeve.com>
* regex_internal.h (__attribute_warn_unused_result__): Always
ifdef out. Bleah.
Thu May 19 17:13:18 2011 Arnold D. Robbins <arnold@skeeve.com>
* Release 3.1.83: Second beta test tar ball for 4.0.
Thu May 19 16:47:19 2011 Arnold D. Robbins <arnold@skeeve.com>
* awkgram.y (dump_vars): Fix warning message. Thanks to Pat Rankin.
* main.c (usage): No space allowed after -d and -p. Also thanks
to Pat Rankin.
Thu May 19 16:34:04 2011 Pat Rankin <rankin@pactechdata.com>
* regex_internal.h (__attribute_warn_unused_result__): Define with
empty expansion for !__GNUC__ configuration.
Wed May 18 22:13:18 2011 Arnold D. Robbins <arnold@skeeve.com>
