It seems I can get rid of FPICFLAGS -fno-common and CPPFLAGS  
-D__DEBUGGING__

If you do not use -lcc_dynamic as LDFLAGS it cannot find restFP and  
saveFP.
/usr/lib/libcc_dynamic.a is a soft link to  
/usr/lib/gcc/darwin/3.3/libgcc.a
which does contain these symbols.

By the way, the symbols are not in  
/usr/local/lib/gcc/powerpc-apple-darwin6.6/3.4/libgcc.a

Also, configure tests if saveFP is in libcc_dynamic.a, and says it  
isn't.
