2002-03-12 Ulrich Drepper <drepper@redhat.com> * posix/bug-regex5.c (main): Use nl_langinfo instead of _NL_CURRENT. * locale/localeinfo.h: Add attribute_hidden to _nl_current_LC_XXX, _nl_category_names, _nl_category_name_sizes, _nl_current, _nl_C_name, _nl_POSIX_name, _nl_C_codeset, and _nl_C_LC_XXX. * intl/dcigettext.c (_nl_default_default_domain): Define as hidden. (_nl_current_default_domain): Likewise (_nl_state_lock): Likewise. * intl/textdomain.c (_nl_default_default_domain): Declare as hidden. (_nl_current_default_domain): Likewise (_nl_state_lock): Likewise. * intl/bindtextdom.c (_nl_state_lock): Likewise. * stdlib/fpioconst.h (__tens): Add attribute_hidden. (_fpioconst_pow10): Likewise. * include/time.h (_tmbuf): Add attribute_hidden. * time/tzset.c (tzstring_list): Define as static. * include/time.h: Add attribute_hidden to __tzname_cur_max and __use_tzfile declaration. * wcsmbs/wcsmbsload.h: Add attribute_hidden to __wcsmbs_gconv_fcts and __wcsmbs_last_locale declaration.
