/* We'll need to define DWORD, BOOL, TRUE and FALSE if someone hasn't
done that before. For now, we'll just assume that if no-one has defined
TRUE we need to define everything. There definitions are compatible with
windows.h. If something else in your system defines these differently,
things should still work OK as long as FALSE is 0, TRUE is nonzero and
DWORD is 32-bit. Take care that you don't compare BOOLs like "bool == TRUE"
in that case though, just use "bool".
THIS IS UGLY AND MAY NEED FIXING!
