you are missing some steps, and some sources.

You need to either check out the "src" module from sources.redhat.com as per
http://sources.redhat.com/gdb/

Use

cvs -z9 -d :pserver:anoncvs@anoncvs.cygnus.com:/cvs/src co src

though, so you get the src module.

-or-

get a binutils tarball from 
ftp.freesoftware.com/pub/sourceware/binutils/snapshots

ie
 
binutils-010122.tar.bz2



Once you have one of these sources (CVS is preferred) you can continue.

Basically, at that point, you'll have

src.src
src.gcc

...and you are going to make a merged tree. One way to to this is:

cp -R src.src src.gcc_merged
cp -R src.gcc/* src.gcc_merged/

You can then use this merged tree to make newlib-based crosses (what you 
are trying to do.)


ie


>         cd /try6/buildgcc

../src.gcc_merged/configure --target=powerpc-eabi 
--prefix=/try6/H-x86-x-powerpc-eabi --enable-languages=c,c++ 
--enable-threads=posix

anyway. This isn't meant to be an exhaustive checklist: Geoff Keating 
wrote up something that's posted either on the gcc lists or on the gcc 
docs pages on the web. You might look for it, as that info is really 
off-topic for this list.
