* locale/setlocale.c (_nl_current_names): Variable moved ...
* locale/localename.c (_nl_current_names): ... here, new file. Make it global, with attribute_hidden. * locale/localeinfo.h: Declare it. * locale/Makefile (aux): Add localename. * locale/localename.c (__current_locale_name): New function. * include/locale.h (__current_locale_name): Declare it. * intl/dcigettext.c (guess_category_value): Use that instead of calling setlocale. * locale/locale.h [__USE_GNU] (locale_t): New type alias of __locale_t. [__USE_GNU] (newlocale, duplocale, freelocale, uselocale): New decls. [__USE_GNU] (LC_GLOBAL_LOCALE): New macro. * locale/newlocale.c: Add alias to __ name. * locale/duplocale.c: Likewise. * locale/freelocale.c: Likewise. * locale/uselocale.c: New file. * locale/Makefile (routines): Add it. * locale/Versions (libc: GLIBC_2.3): New set. Add newlocale, duplocale, freelocale, uselocale. (libc: GLIBC_PRIVATE): Add __uselocale. * locale/localeinfo.h [SHARED] (_NL_CURRENT_LOCALE): New macro, defined to fetch a tsd value. (_NL_CURRENT_DATA): Define using that. (_NL_CURRENT, _NL_CURRENT_WSTR, _NL_CURRENT_WORD): Define using that. (_NL_CURRENT_DEFINE): Define to empty. [! SHARED]: Decls of _nl_current_CATEGORY and _nl_current conditionalized on this. * locale/xlocale.c (NL_C_INTIIALIZER): New macro, taking initializer of _nl_C_locobj. [SHARED] (_nl_global_locale): New variable, using that initializer. (_nl_C_locobj): Use new macro for initialzier. * locale/setlocale.c [! SHARED] (_nl_current): Conditionalize on this. [! SHARED] (CATEGORY_USED): New macro. [SHARED] (CATEGORY_USED, _nl_C): New macros. (setdata, setlocale): Use that macro instead of examining _nl_current. (setdata): Set the slot in _nl_global_locale. Conditionalize setting of _nl_current on [! SHARED]. * locale/findlocale.c [SHARED] (_nl_C): Define as a macro instead of declaration as an extern. * locale/newlocale.c (__newlocale): Use _nl_C_locobj instead of _nl_C. * include/locale.h: Use libc_hidden_proto for setlocale. * locale/setlocale.c: Add libc_hidden_def. * locale/setlocale.c (free_mem): Use _NL_CURRENT_DATA.
