I've been reading through "More Tricks of the Game Programming Gurus",
and one of the chapters uses self-modifying code to speed up its sprite
rotation algorithm.  I'd love to use that technique in DJGPP's inline
ASM, but I don't know the syntax.  I've tried things like

    movl $0,%edx
label:
    movl _stuff,label-4

but the compiler doesn't seem to like it.  I'm sure it will allow me to
do it, with a flat memory model, but I think I'm just doing it wrong.

Help!  I'm running out of registers! :)
