RE: In great Need of some Educate'n
Thank you Andrew.
I needed a place to start.
Re: <my path info>, I edited out my pathing info for the posting. I can
be paranoid some times.

1.3.1? What breed of dinosaur was he?

The documentation is a good place to start.
The old 1.3.1 documents are still available:
http://ecos.sourceware.org/docs-1.3.1/
However the concepts for building eCos have not changes since
prehistoric times, so reading the last documents about how to build eCos
is also O.K.

If your configuration includes them. Do you still have the configuration
information?

Err, weren't you suppose to replace <my path info> with something? Are
you following somebodies instructions? Normally you replace <foobar>
with a real path.

You might want to look at
http://ecos.sourceware.org/cgi-bin/cvsweb.cgi/ecos/packages/hal/powerpc/
arch/current/include/arch.inc?cvsroot=ecos
and in particular the last change, "Update for newer GCC/GAS"
