Speaking of this, does anyone know of any reason -why- ANSI C specifies
this? Or did someone just go off on a whim and say "Hey! Let's make
setjmp a macro, and break interfacing to every other language! Yeah!"?

There was a machine on which implementing setjmp as a function was
difficult if not impossible. (I don't remember the machine or the
details; it was something to do with not being able to access the
frame pointer for anything besides the current procedure.)
Calling setjmp from a language other than C is not a particularly
good idea anyway; for example if the interface is implemented using
stub routines setjmp won't work at all. The difficulty GNAT faces
is that the method of performing a setjmp is machine-specific but
is not specified in the machine descriptions used by GCC.

Yes! Up on cs.nyu.edu you will find gnat-2.04-linux*.
