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
crosstest.

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)
