David ...

No problem on the delay. I understand the problem ... ;-)

I'm using HP-UX 9.01 on an HP700s.  I started with the "GCC" version of
"machine.h" and "makefile".  After running "./configure", the "machine.h" 
file which is generated "#include'd <malloc.h>" before <stdio.h> (which 
the HP version of "cc" does not like).  My amended version of "machine.h" 
is included below; the differences start around line 68.  

Also, the "cc" compiler seems to require "-Aa" to be put in the CFLAGS in the
makefile (this option forces ANSI compatibility).  Otherwise, the library and
its entries are created, but the functions do not seem be accessible from 
code.  Also, the ".o" files which are created without the "-Aa" are on the
order of ~400 bytes ... a bit small from my experience.  With the "-Aa", the
object files are 1K or 2Kbytes.  Several "redefinitions of macro HUGE_VAL" 
also occur at compilation which don't seem to be a problem.

These changes seem to generate the "meschach.a" library ok.  Let me know if I
can help further.
