/*
This port.h is really a right-of-passage for anyone trying to port the emulator
to another platform. It must have started out as a set of defines for a
single platform, and instead of using define blocks as new platforms were
added, individual coders simply added exceptions and sprinkled #ifdef and #ifndef
statements throughout the original list.
I can't take it anymore, it's too convoluted. So I've commented out the entire
section, and preemptively rewritten the first #define segment the way god intended,
with a single define-block for each target platform.
