Yes they're OK, but they're one more thing. Compiling these .o files slows down 
the build and lengthens the build log slightly. People who read the build logs 
will reasonably wonder "why is a w32 file being compiled on a non-w32 platform"?

So if it's a choice of level and either possibility is easy, I'd rather see this 
done at the "should I compile this .c file?" level, rather than at the "should 
this .c file be empty?" level.
