annotate lib/regex_internal.h @ 8153:0f48fdcc7a64

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Fix regex code so it doesn't rely on strcasecmp. * lib/regex_internal.h: Include <langinfo.h> only if _LIBC is defined. Otherwise, include gnulib's langinfo.h. * lib/regcomp.c (init_dfa): Don't use strcasecmp, as it can have undesirable behavior in non-C locales. Instead, rely on locale_charset. * m4/regex.m4 (gl_PREREQ_REGEX): Don't require AM_LANGINFO_CODESET. * modules/regex (FILES): Remove m4/codeset.m4. (Depends-on): Add localcharset. Remove strcase.
