2010-08-18compat/regex: use the regex engine from gawk for compatLibravatar Ævar Arnfjörð Bjarmason1-0/+810
Change the regex engine in compat to use the gawk engine from the gawk-devel module in gawk CVS. This engine supports the REG_STARTEND flag, which was optionally available in Git since v1.7.2-rc0~77^2~1. The source was grabbed from cvs.savannah.gnu.org:/sources/gawk, and these are the upstream versions of the files being included: regcomp.c 1.4 regex.h 1.3 regex.h 1.3 regex_internal.c 1.3 regex_internal.h 1.3 regexec.c 1.3 Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Acked-by: Jonathan Nieder <jrnieder@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
