The following test application fails to build on i686 when building
without optimization:
$ cat foo.c
#include <windows.h>
int
main ()
{
MEMORY_BASIC_INFORMATION m;
NT_TIB *tib = (NT_TIB *) NtCurrentTeb ();
VirtualQuery (tib, &m, sizeof m);
}
$ gcc -g -O foo.c -o foo
$ gcc -g foo.c -o foo
/tmp/ccnnAEl3.o: In function `main':
/home/corinna/foo.c:7: undefined reference to `NtCurrentTeb'
collect2: error: ld returned 1 exit status
There's no way around that, except for building with optimization, which
is often not prudent when debugging.
In winnt.h, NtCurrentTeb is using __CRT_INLINE which, depending on C
standard, expandes into
extern inline __attribute__((__gnu_inline__))
or
extern __inline__
However, that's not sufficient for NtCurrentTeb, nor for GetCurrentFiber,
nor for GetFiberData, since these are inline-only functions not backed by
non-inlined library versions.
This patch fixes that by using FORCEINLINE in place of __CRT_INLINE.
