[BZ #693]
Update. 2005-01-26 Jakub Jelinek <jakub@redhat.com> * sysdeps/unix/sysv/linux/i386/sysdep.h (SYSCALL_ERROR_HANDLER_TLS_STORE): Remove unnecessary 0 imm. [BZ #693] * posix/regex_internal.h (DUMMY_CONSTRAINT): Rename to... (WORD_DELIM_CONSTRAINT): ...this. (NOT_WORD_DELIM_CONSTRAINT): Define. (re_context_type): Add INSIDE_NOTWORD and NOT_WORD_DELIM, change WORD_DELIM to use WORD_DELIM_CONSTRAINT. * posix/regcomp.c (peek_token): For \B create NOT_WORD_DELIM anchor instead of INSIDE_WORD. (parse_expression): Handle NOT_WORD_DELIM constraint. * posix/bug-regex19.c (tests): Adjust tests that relied on \B being inside word instead of not word delim. * posix/tst-rxspencer.c (mb_frob_pattern): Don't frob escaped characters. * posix/rxspencer/tests: Add some new tests.
