[Distutils] gcc compiler options' override

Hi, For a couple comps, like: . RuleDispatch-0.5a0.dev-r2115.tar.gz . cElementTree-1.0.5-20051216.zip, ... I'm trying to build and deploy them as eggs... Using the $CC override, I'm able specify the compiler of choice to compile the C sources in these comps. How do I select the compiler options ( -I, -L, -D etc) and have them picked up by the compiler (--compiler=unix) which in turn could be used by distutils.unixcompiler... Thanks, /venkat
