Update.
2000-01-18 Ulrich Drepper <drepper@cygnus.com> * posix/regex.h (RE_SYNTAX_POSIX_EXTENDED): Add RE_CONTEXT_INVALID_OPS. * posix/regex.c (regex_compile): Return appropriate errors for unterminated brace expressions. Detect invalid characters in brace expressions. * posix/bits/posix2_lim.h: Define RE_DUP_MAX correctly. * sysdeps/posix/sysconf.c: Include regex.h. Reported by Geoff Clare <gwc@unisoft.com> (PR libc/1522).
