When gnulib redefines mbstate_t, it also needs to override the system's
mbsrtowcs implementation. Needed in particular on AIX.
2008-12-20 Bruno Haible <address@hidden>
* lib/wchar.in.h (mbsrtowcs): Redefine if REPLACE_MBSRTOWCS is set.
* m4/mbsrtowcs.m4 (gl_FUNC_MBSRTOWCS): Invoke gl_MBSTATE_T_BROKEN. Set
REPLACE_MBSRTOWCS if mbsrtowcs needs to be overridden.
* m4/wchar.m4 (gl_WCHAR_H_DEFAULTS): Initialize REPLACE_MBSRTOWCS.
* modules/wchar (Makefile.am): Substitute REPLACE_MBSRTOWCS.
