Rather than editing config.h to set the correct s- and m- files, why not
#include system.h and machine.h, then make those files be links to the
correct m- and s- files? I believe this is the way the GNU C compiler build
stuff is set up. Most of the time, the only change needed to config.h is to
edit in the proper .h files. 

I bring this up because I think the config.gcc stuff is pretty useful,
especially since the proper distinction between system and machine files has
never quite existed in Emacs. (Read the Sun section in etc/MACHINES for a
taste of that.)

Based on the contents of /etc/MACHINES, I hacked config.gcc into
config.emacs a few months ago.  It has not been well-tested, since I only
have access to a couple of Sun architectures.  Do with it as you wish.
