When <basetyps.h> defines wchar_t, it must obey -f(no-)short-wchar by referring to __WCHAR_TYPE__ which may not be `unsigned short`.
Similarly, windef.h defining NULL may need to use GCC's __null. Otherwise one-definition-rule problems arise depending on whether wine or libc headers are included first.
tchar.h wint_t and wctype_t are defined by <wchar.h>, which was already being included.
Implementing these by deferring to the C89-specified libc headers, (or msvcrt's versions with -mno-cygwin) ensures matching definitions.

<basetyps.h> uses gcc's __need_* macros to document/filter that it only intends to define wchar_t (and not the rest, e.g. size_t/ptrdiff_t) to match the names defined by the MSVC version as closely as possible. That's not portable, but if not supported it'll just get the rest too, which is unlikely to really hurt anything in practice.
<windef.h> always ended up with all of <stddef.h> later (via <winnt.h>), and the real SDK header does to, so there's no reason to be subtle there. --- include/basetyps.h | 8 +++++--- include/tchar.h | 9 --------- include/windef.h | 9 +++++---- 3 files changed, 10 insertions(+), 16 deletions(-)
