Yes. The problem is that mbstate_t is #defined to rpl_mbstate_t (due to
a bug in the mbrtowc function), but wcrtomb is left alone by gnulib.
This fixes it.
2009-05-01 Bruno Haible <address@hidden>
* lib/wchar.in.h (wcsnrtombs): Define if REPLACE_WCSNRTOMBS is 1.
* m4/wcsnrtombs.m4 (gl_FUNC_WCSRTOMBS): Invoke gl_MBSTATE_T_BROKEN, and
set REPLACE_WCSNRTOMBS if mbstate_t must be replaced.
* m4/wchar.m4 (gl_WCHAR_H_DEFAULTS): Initialize REPLACE_WCSNRTOMBS.
* modules/wchar (Makefile.am): Substitute REPLACE_WCSNRTOMBS.
* modules/wcsnrtombs (Files): Add m4/mbrtowc.m4, m4/locale-ja.m4,
m4/locale-zh.m4, m4/codeset.m4.
* m4/wcsrtombs.m4 (gl_FUNC_WCSNRTOMBS): Invoke gl_MBSTATE_T_BROKEN, and
set REPLACE_WCSRTOMBS if mbstate_t must be replaced.
* modules/wcsrtombs (Files): Add m4/mbrtowc.m4, m4/locale-ja.m4,
m4/locale-zh.m4.
* m4/wcrtomb.m4 (gl_FUNC_WCRTOMB): Invoke gl_MBSTATE_T_BROKEN, and set
REPLACE_WCRTOMB if mbstate_t must be replaced.
* modules/wcrtomb (Files): Add m4/mbrtowc.m4.
