I appreciate the advice. I think what I decided should be done, is I should
hack in a command line option that can be used as a conditional, so that way
GCC can be compiled with all of its functionality, so that it can faithfully
recompile itself, and I can just add that option in the make routines.

I went to compile a "tainted" build last night, but I ran into a build error
apparently related only to subversion checkouts, which might also be
particular to the target debian distribution / hardware support for some
esoteric reason according to what can be gleamed from google. So I went to
just download the release sources, but all of the mirrors were down for some
reason. 

The error is related to a bison/flex build event, which for some reason
can't be completed by autotools or something... I figure it easier to just
go with the release sources as suggested (the relevant .c files are
pregenerated in the release trees)
