<locale.h> is specified to define locale_t in POSIX.1-2008, and so are all of the headers that define functions that take locale_t arguments. Under _GNU_SOURCE, the additional headers that define such functions have also always defined locale_t. Therefore, there is no need to use __locale_t in public function prototypes, nor in any internal code. * ctype/ctype-c99_l.c, ctype/ctype.h, ctype/ctype_l.c * include/monetary.h, include/stdlib.h, include/time.h * include/wchar.h, locale/duplocale.c, locale/freelocale.c * locale/global-locale.c, locale/langinfo.h, locale/locale.h * locale/localeinfo.h, locale/newlocale.c * locale/nl_langinfo_l.c, locale/uselocale.c * localedata/bug-usesetlocale.c, localedata/tst-xlocale2.c * stdio-common/vfscanf.c, stdlib/monetary.h, stdlib/stdlib.h * stdlib/strfmon_l.c, stdlib/strtod_l.c, stdlib/strtof_l.c * stdlib/strtol.c, stdlib/strtol_l.c, stdlib/strtold_l.c * stdlib/strtoll_l.c, stdlib/strtoul_l.c, stdlib/strtoull_l.c * string/strcasecmp.c, string/strcoll_l.c, string/string.h * string/strings.h, string/strncase.c, string/strxfrm_l.c * sysdeps/ieee754/float128/strtof128_l.c * sysdeps/ieee754/float128/wcstof128.c * sysdeps/ieee754/float128/wcstof128_l.c * sysdeps/ieee754/ldbl-128ibm/strtold_l.c * sysdeps/ieee754/ldbl-64-128/strtold_l.c * sysdeps/ieee754/ldbl-opt/nldbl-compat.c * sysdeps/ieee754/ldbl-opt/nldbl-strfmon_l.c * sysdeps/ieee754/ldbl-opt/nldbl-strtold_l.c * sysdeps/ieee754/ldbl-opt/nldbl-wcstold_l.c * sysdeps/powerpc/powerpc32/power7/strcasecmp.S * sysdeps/powerpc/powerpc64/power7/strcasecmp.S * sysdeps/x86_64/strcasecmp_l-nonascii.c * sysdeps/x86_64/strncase_l-nonascii.c, time/strftime_l.c * time/strptime_l.c, time/time.h, wcsmbs/mbsrtowcs_l.c * wcsmbs/wchar.h, wcsmbs/wcscasecmp.c, wcsmbs/wcsncase.c * wcsmbs/wcstod.c, wcsmbs/wcstod_l.c, wcsmbs/wcstof.c * wcsmbs/wcstof_l.c, wcsmbs/wcstol_l.c, wcsmbs/wcstold.c * wcsmbs/wcstold_l.c, wcsmbs/wcstoll_l.c, wcsmbs/wcstoul_l.c * wcsmbs/wcstoull_l.c, wctype/iswctype_l.c * wctype/towctrans_l.c, wctype/wcfuncs_l.c * wctype/wctrans_l.c, wctype/wctype.h, wctype/wctype_l.c: Change all uses of __locale_t to locale_t.
