OpenServer 5.0.7: setsockopt(TCP_NODELAY)?

I asked my friends at SCO (who are productizing PG) to test
7.4RC1 on OpenServer 5.0.7, and received this back:

A "make check" fails at createdb with errors in the postmaster logfile:

LOG: setsockopt(TCP_NODELAY) failed: Protocol not available

Plus he needed to add:

if test "$GCC" != yes ; then
CC="$CC -b elf"
fi

to src/template/sco for 5.0.7.
I downloaded 7.4 RC1 and successfully compiled it on an OpenServer 5.0.7
system.
I am attaching the only change i had to make. This is the file
src/template/sco.
The GCC compiler on OSR5 no longer accepts the "-b elf" argument.

Anyone of the guru's have ideas?

Thanks,
LER
