Fix mbrtowc so that it never returns -1 in the C locale, as this conflicts with a future version of POSIX http://austingroupbugs.net/view.php?id=663#c2738 and causes problems with GNU grep: http://bugs.gnu.org/23234 See glibc bug 19932: https://sourceware.org/bugzilla/show_bug.cgi?id=19932 * doc/posix-functions/mbrlen.texi (mbrlen): * doc/posix-functions/mbrtowc.texi (mbrtowc): Document the glibc bug. * lib/mbrtowc.c [C_LOCALE_MAYBE_EILSEQ]: Include hard-locale.h, locale.h. (rpl_mbrtowc): Work around the C_LOCALE_MAYBE_EILSEQ bug, if the bug is possible. * m4/mbrtowc.m4 (gl_MBRTOWC_C_LOCALE): New macro. (gl_FUNC_MBRTOWC): Use it, and define C_LOCALE_MAYBE_EILSEQ as needed. * modules/hard-locale (License): Now LGPLv2+, for mbrtowc. * modules/mbrtowc (Depends-on): Add hard-locale. * modules/mbrtowc-tests (Files, TESTS): Add tests/test-mbrtowc5.sh. * tests/test-mbrtowc.c (main): Test for bug fix if arg is '5'. * tests/test-mbrtowc5.sh: New file.
