From b9ea2dd05ee1684ca36ce7ee62ac679f391b6a7f Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Sat, 27 Mar 2010 06:06:35 -0700 Subject: Fix handling of __need_mbstate_t and __need_wint_t. Like the real header, the libc-internal wrapper for wchar.h needs to undefine the macros so that if the header was already included before the macros don't stay defined and cause problems later. --- include/wchar.h | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'include') diff --git a/include/wchar.h b/include/wchar.h index bca847731d..3afe0b6e2e 100644 --- a/include/wchar.h +++ b/include/wchar.h @@ -195,3 +195,8 @@ extern size_t __mbsrtowcs_l (wchar_t *dst, const char **src, size_t len, # endif #endif + +/* Undefine all __need_* constants in case we are included to get those + constants but the whole file was already read. */ +#undef __need_mbstate_t +#undef __need_wint_t -- cgit v1.2.3
