changeset 7110:f4969cab8e44
Import the following changes from libc:
2006-06-02 Jakub Jelinek <jakub@redhat.com>
* posix/regex_internal.c (re_string_skip_chars): If no character has
been converted at all, set *last_wc to WEOF. If mbrtowc failed, set wc
to the byte which couldn't be converted.
(re_string_reconstruct): Don't clear valid_raw_len before calling
re_string_skip_chars. If wc is WEOF after re_string_skip_chars, set
tip_context using re_string_context_at.
2006-05-02 Ulrich Drepper <drepper@redhat.com>
* posix/regex.h: g++ still cannot handled [restrict].
2006-04-21 Ulrich Drepper <drepper@redhat.com>
* posix/regex.h: Remove special handling for VMS.
