[HELP] GCC 4.1 branch Ada status on powerpc-darwin?

That's not sufficient: the compiler bootstraps fine, but all the ACATS tests 
fail to link:

gnatlink a22006c.ali 
--GCC=/nile.build/botcazou/gnat6/powerpc-apple-darwin8/gcc/
xgcc -B/nile.build/botcazou/gnat6/powerpc-apple-darwin8/gcc/
/usr/bin/ld: warning -L: directory name

So, on Darwin, unlike any other platforms, you need to explicitly pass either 
-static-libgcc or -shared-libgcc to link the EH machinery.  That seems weird.

Geoff, any chance to bring Darwin back on par with the other platforms?
