Ya, it should work. I was only building test applications using the
cl from the platform SDK in wine; I haven't been using it for make

That doesn't make sense, because I am primarily using gcc in Ubuntu.
Did you try it with the parentheses, because unary minus has higher
precedence than division:
-0.0f/zero => -nan (0xffc00000)
-(0.0f/zero) => nan (0x7fc00000)
