Problems building (fuzzy) CLIPS on Redhat 8.0

Hi,

I'm trying to compile the (Fuzzy) CLIPS source on an Intel/Redhat 8.0 
platform. I get a bunch of messages stating that the following header 
files are missing:

stdsyms.h
_inttypes.h
sigevent.h
siginfo.h
newsig.h
stdarg.h
varargs.h

After a little research, I have realised that these are mostly (if not 
all) required for the HP platform. This led me to suspect the setup.h 
file. Sure enough it had been setup for UNIX_V = 1. This for Unix System 
V or HP Unix. The problem is that (as far as I know), Redhat 8.0 is 
based of System V. A further ook at the Makefile.cl and Makefile.x shows 
that there is an explicit (hard coded) dependency  of some object files 
(e.g. agent.o etc) on some of these header files.

Has any one sucessfully managed to compile CLIPS on an Intel/Redhat 
platform?. If so, I would greatly appreciate your help. I can send you a 
private email address so that you can send me copies of your setup.h and 
makefile.* files or if the changes to be made are simple enough, you may 
 simply outline it in an email to this group.

Looking forward to your help.

Thanks
