OS    = SCO OpenServer 5.0.6a
UDK 7.1.1a

Develpement Environments
====================
Native           - SCO UNIX Development System  Release 5.1.2A 27Jul00
UDK 7.1.1a  - Optimizing C Compilation System  (CCS) 3.2 09/28/99
                        (santamariasbl5.1.rs1ubl7)
gcc                - version 2.95.2 19991024 (release)

This gives me 3 options /usr/bin/cc, /udk/usr/ccs/bin/cc and
/usr/local/bin/gcc

gcc fails test compile at the end of configure

udk fails displays multiple warning: no SCO ELF identifying .note and
others
then fails to link

/usr/bin/cc gets the closest

Any help sorting this out would be appreciated.
In the mean time I'm working my way back through the available versions
to see if this is something that broke in one of the newer releases.

Attached is the config.log for the udk attempt.

Thank you Steve
