We had the very same problem when we first tried using gcc. We
need the "sunmath" library for the nint() function, so we
used the rint() function instead and casted the result. Follow
this example and try to replace any functions that require the
"sunmath" library.

We've been using gcc to create shared-object .so libraries that
are called from within IDL using CALL_EXTERNAL, with no problems.
This is the reverse of what you're doing, but I don't think there
would be any problems.
