Host/Target specific installation notes for GCC - GNU Project - Free Software Foundation (FSF)

Does anyone know how to build a cross-compiler to produce sparc-v7  
executables on a Mac OS X / Darwin host?

Whenever I try to build gcc using the target sparc-aout I get the  
following error message:

<command line>:1:10: warning: "cpu" re-asserted

I am trying to compile gcc-3.1 on OS X 10.2.1 :  the binutils  
compilation for sparc-aout worked just fine.

Thanks.
