Someone just posted a patch that would enable that functionality, if
it works.

Now wait a minute.  If you download and build GCC from source, you
pretty much have to install it with a nonstandard prefix or your
system will get messed up, and I do that all the time.  You don't need
to do anything about #include paths, but the LD_LIBRARY_PATH and,
possibly -L, do need to be set differently.
