I think the purpose of
#define NOUSER
is to use it before
#include <windows.h>
to speed compiles when you know that you won't be calling any functions in
winuser.h
This feature appears to be broken in the 20080608 snapshot (I'm using
mingw-w64-bin_i686-cygwin-1.5.25-14_20080608)
This code demonstrates the problem:
#define NOUSER
#include <windows.h>
int main()
{
}
When compiled this way:
x86_64-pc-mingw32-gcc -o test nouser.c
It produces these errors (excerpt):

I discovered this trying to build cppunit 1.12.1, which uses this feature
