GCC executable

[Stewart, Ahamadou V. [C]]

To whom it may concern,
     I am working on HP-UX 10.20. I am simply trying to compile xemacs with
gcc-3.0.1 compiler. I have the executable gcc in /usr/local/bin. I set up
the CC variable to /usr/local/bin/gcc. Based on the compiling script for the
xemacs, it looks for the C compiler where ever you specify in the variable.
I think it defaults to /usr/ccs/bin/cc. But cc will not complete the
compile. Every time I use the gcc compiler, it does not work. But when I use
the cc compiler it tries to compile but it does not complete the compile. So
my question is why is my gcc compiler  not  working? Can I get some tips on
how to simply make the compiler work? So I can make xemacs work.
