* bits/types.h: Don't include stddef.h, don't define __need_size_t.

Browse Source 
* signal/signal.h <__USE_BSD || __USE_XOPEN_EXTENDED>: Define
	__need_size_t and include stddef.h.
	* sysvipc/sys/msg.h: Likewise.
	* posix/sched.h: Likewise.
	* hurd/hurd/signal.h (__need_size_t): Define.

	* CONFORMANCE: ctype.h and wctype.h no longer define size_t,
	neither does signal.h in pedantic ISO C namespaces.  stdio.h
	no longer defines wint_t or wchar_t.

CONFORMANCE
View File

@ -184,15 +184,7 @@ Also, the Single Unix Specification generally requires more types to
be included in headers (if _XOPEN_SOURCE is defined appropriately)
than ISO C permits.
<ctype.h> should not declare size_t.
<signal.h> should not declare size_t.
<stdio.h> should not declare or use wchar_t or wint_t.
<wchar.h> does not support AMD1; to support it, the functions
fwprintf, fwscanf, wprintf, wscanf, swprintf, swscanf, vfwprintf,
vwprintf, vswprintf and fwide would need to be declared when
__STDC_VERSION__ >= 199409L and not just for C99.
<wctype.h> should not declare size_t.
