* iconv/gconv_int.h (__GCONV_NULCONV): New internal only error code.
* iconv/gconv_cache.c (__gconv_lookup_cache): Return __GCONV_NULCONV if from and to charsets are the same. * iconv/gconv_db.c (__gconv_find_transform): Likewise. * intl/dcigettext.c (_nl_find_msg): Return NULL even if __gconv_open returns __GCONV_NOCONV, but not for __GCONV_NULCONV. 2007-07-17 Jakub Jelinek <jakub@redhat.com> * wcsmbs/wchar.h: Only define wint_t if __need_wint_t. Don't define wint_t when __need_mbstate_t unless it is necessary. (__mbstate_t): Use __WINT_TYPE__ rather than wint_t in the typedef if possible. * wctype/wctype.h (wint_t): Define by including wchar.h with __need_wint_t instead of including stddef.h with __need_wint_t and as fallback definining it ourselves. * iconv/gconv.h (__need_wint_t): Define before including wchar.h. * sysdeps/gnu/_G_config.h: Don't include gconv.h if not _LIBC or _GLIBCPP_USE_WCHAR_T. (__need_wchar_t): Don't define if not _LIBC or _GLIBCPP_USE_WCHAR_T. (__need_wint_t): Don't define before including stddef.h, define before including wchar.h only if _LIBC or _GLIBCPP_USE_WCHAR_T. (_G_iconv_t): Don't define if not _LIBC or _GLIBCPP_USE_WCHAR_T. * sysdeps/mach/hurd/_G_config.h: Likewise. * sysdeps/generic/_G_config.h: Likewise. * libio/libio.h (__wunderflow, __wuflow, __woverflow): Only prototype if _LIBC or _GLIBCPP_USE_WCHAR_T. (_IO_getwc_unlocked, _IO_putwc_unlocked): Only define if _LIBC or _GLIBCPP_USE_WCHAR_T.
