Thanks Erik,
Question, when you say "cvs up and try again," which tree in the
toolchain source (3.2, 3.2.1, etc) are you updating? I just cvs up'ed
the whole toolchain tree and got nothing new, and ViewCVS (web) doesn't
show any update either.
BTW, another question: What is the best way to get the toolchain
optimized for a particular processor? So far, what I'm doing is editing
the make file to include something like
CONFIG_OPTS=--with-cpu=403 --nfp --without-fp
and then adding this variable to the configure statements used to build
gcc. Is there another way to do it?
