Ulrich Drepper 4c595adb60 Update.
2004-02-29  Paolo Bonzini  <bonzini@gnu.org>

	* posix/regexec.c (transit_state): Don't handle state == NULL.
	Move state log and backreference management...
	(merge_state_with_log): ... to this function.
	(find_recover_state): New function.
	(check_matching): Use find_recover_state to get a non-NULL
	state when an invalid state is reached.  Compute the amount
	of initial characters to be skipped less conservatively when
	multi-byte character sets are in use.  Do not check
	dfa->nbackref if the state log is NULL.  Initialize err.
	(acquire_init_state_context): Expect err to be initialized.
	Fix spacing.

2004-03-05  Jakub Jelinek  <jakub@redhat.com>

	* sysdeps/sparc/sparc32/elf/start.S: Handle PIEs.
	* sysdeps/sparc/sparc64/elf/start.S: Likewise.
