* locale/xlocale.c: Revert changes putting _nl_global_locale here. This file again just defines _nl_C_locobj. (_nl_C_locobj): Use a categories.def iterator in the initializer. * locale/global-locale.c: New file. Define _nl_global_locale here, using all weak references in the initializer. * locale/Makefile (aux): Add global-locale. * locale/localeinfo.h (_nl_global_locale, _NL_CURRENT_LOCALE): Make these unconditional, along with the tsd decl. [!SHARED && HAVE___THREAD && HAVE_WEAK_SYMBOLS] (NL_CURRENT_INDIRECT): Define it under these conditions. [NL_CURRENT_INDIRECT]: Test this instead of [! SHARED]. Don't declare _nl_current. Declare _nl_current_LC_FOO as `extern __thread struct locale_data *const *'. [NL_CURRENT_INDIRECT] (_NL_CURRENT_DATA, _NL_CURRENT, _NL_CURRENT_WSTR): Add indirection. [NL_CURRENT_INDIRECT] (_NL_CURRENT_DEFINE): Rewritten. Define the thread variable _nl_current_LC_FOO and also a special absolute symbol _nl_current_LC_FOO_used. * locale/uselocale.c (__uselocale) [NL_CURRENT_INDIRECT]: Set each _nl_current_LC_FOO symbol to point into the new locale, using weak references to test if _nl_current_LC_FOO_used was linked in. * locale/setlocale.c [! SHARED]: Replace this conditional ... [NL_CURRENT_INDIRECT]: ... with this one. (_nl_current, _nl_C): Variables removed. [NL_CURRENT_INDIRECT] (_nl_current_used): New variable, table of weak references to _nl_current_LC_FOO_used. [NL_CURRENT_INDIRECT] (CATEGORY_USED): Define using that table. (free_category): New function, broken out of ... (free_mem): ... here. Call that. (free_mem) [NL_CURRENT_INDIRECT]: Use a categories.def iterator instead of a loop. __USING_NAMESPACE_C99 depending on _GLIBCPP_USE_NAMESPACES.
