Ping Re: PowerPC E500 port

[Roland McGrath]

Please don't use compressed attachments.  Just put the patches in your
email with the least amount of encoding you can manage.

I don't think the main powerpc files should do conditional includes of
nonexistent files like that.  Instead, have your port override with a file
that #include's the main file.  If you need to modify the main files to
facilitate that, I think a pure macro #ifdef bit without an #include is better.
You can use a gas macro in your file to make defining the part with your
code prettier than a big #define.

For changes to powerpc files in the main tree, you should get an OK from
Steve Munroe <sjmunroe@us.ibm.com> and then post to libc-alpha.  For the
ports additions, with an OK from Steven and general review from me or
Daniel, one of us can commit it.


Thanks,
Roland
