My advice is to always use the gcc that your vendor recommends.  If you
do not have a vendor, find one and see what they recommend.. <grin>  The
easiest vendor to see is the ELDK.

Note, thos recommendations in the Documentation file are generally
specific to x86.  PPC the newer gcc compilers are sometimes required for
different architectures.
