Can you attach the patch as a text/plain please?   That way it's easier to
deal with.  Thanks.

dietlibc patch to get rid of the gcc3 warnings

------- Comment #3 From Mr. Bones. 2004-02-19 18:53:37 0000 ------- 
Fixed in CVS.  I didn't bump the revision on the ebuild since I believe the
newer versions of gcc will still work with the old options, but warn about them.
Let me know if this isn't the case and I'll rev bump the ebuild to make people
upgrade.  Remerge dietlibc to get the change if you have it currently installed
and want to get the patch.
