OK, first things first. When asking for help, it's best to
direct the question to a mailing list rather than directly
to the author. firstname.lastname@example.org is a good list for
this question; it's also the one the crosstool doc recommends.
When posting to a mailing list, please set your email client to
send plain text and to wrap outgoing mail at 80 columns
(or do it yourself); long lines and HTML mail may get your mail ignored.
Second, http://kegel.com/academy/opensource.html has an introduction
to patches which may help.
Third, all the patches in crosstool are diffs from the parent
directory of gcc-x.y, so you'll need to edit that patch
to insert gcc-foo/ in front of the paths before it can be accepted.
Fourth, you might want to check whether that patch is already in
a newer version of gcc, say, gcc-3.3.3 or gcc-3.3.4; it might be
easier to just update than to patch.
Fifth, you should probably use crosstool-0.28-rc28 rather than crosstool-0.27.
Good luck, and please address future questions to the mailing list
rather than to me directly.
