What's in your <stdmacro.h> /prog/?

I always thought these were a bad idea. There's too much temptation to put everything in one big header and include it everywhere, even when it's not needed - this can slow down compilation by quite a bit.

I always break things up, even when the length of the header file doesn't make it seem like a necessary thing. My bit.h is like 15 lines, for example.  If you've ever had to split up a big header file, you'll appreciate the reason for this.
