I am having troubles with this patch as it will not apply against a clean
uncompress of gcc-3.4.1.tar.bz2 from gcc.gnu.org <http://gcc.gnu.org> I have
compared and the timestamp the patch is looking for is 6 hours ahead of the
one from the archive

I don't want to use a different version of gcc as I have stuff that I
recompile often that needs to be compiled with the same version of gcc as
other stuff which I don't want to start recompiling and multiple gcc
versions just seems messy to me as I have had it before and had confusion
