Sorry, what I meant to say is I'm not sure if these are compatible
with "cc". I will give this a try, although I prefer sticking with
"cc" because this compiler is kept more up-to-date.

This is the same for IRIX. I looked at the site.cfg file and only
saw two lines. I'll see if I can use it to help it look for 64-bit
libraries.
