Hope that subject line was descriptive enough...

I would like to ask for help installing a binary distribution
of gcc and g++ for SCO Xenix.
I downloaded SCO Xenix binaries for gcc 1.37.1 and g++ 1.37,
apparently using Steve Bleazard's patches.  I am using SCO Xenix
2.3.4 with the SCO Xenix Development System 2.3.1.

Gcc and g++ execute and compile programs, but do not link programs.
I have only tried to compile "hello world" programs in C and C++,
respectively.  
I do not have gnu-ld, so gcc and g++ are using /bin/ld.
I will include here the ld commands used by gcc and g++,
and the (paraphrased) error output of compiling foo.c and foo.cc.

What am I doing wrong?
