* Update.Ulrich Drepper2004-12-271-47/+47
| | | | | | | | | | | | 2004-04-27 Paolo Bonzini <bonzini@gnu.org> * posix/regex_internal.h (struct re_dfastate_t): Make word_trtable a pointer to the 512-item transition table. * posix/regexec.c (build_trtable): Fill in either state->trtable or state->word_trtable. Return a boolean indicating success. (transit_state): Expect state->trtable to be a 256-item transition table. Reorganize code to have less tests in the common case, and to save an indentation level.
