At line 1506 in cobpre.c, ATTRIBUTE_UNUSED is included in the function
definition for some reason.  Didn't think it was supposed to be there,
as it's not in the prototype.  Build goes along pretty well without
that, until it reaches a point of looking for install-sh or install.sh. 
Thought I had autogen installed--I'll double check.

I've got a more-or-less RedHat system as well.  gcc is 2.95.2.  Think I
need autogen to finish the build, though...I'll double check that and
try again after work tonight
