fix for darwin/sbcl matlisp build

I tryed a more recent version of autoconf (version 2.59) but that didn't 
  help anything.  Same problem as before.

Then I tried to fiddle with the configure.in file.  It is only the 
"AC_F77_FUNC(f77_name)" command which causes problems on darwin so I 
just put that behind a case statement and hardcoded in the correct 
answer for darwin.  This function still gets called on non-darwin platforms.

With this change everything works.  I've attached the patch for 
configure.in.  Public cvs seems to be down so I may have generated the 
patch incorrectly, if I did a full verison of the new configure.in file 
is at
http://mercury.chem.pitt.edu/~rds/

Also newer versions of config.sub and config.guess are needed for 
configure to recognize darwin correctly.  These are in the autoconf 
distribution and I also put copies on my web site.
