That's not a problem: I can rearrange these however I want/need to do
it.

Whoa, wait a minute.  There's no --sysroot option to GCC; sysroot is a
CONFIGURE-time option (--with-sysroot).  That's why I have to rebuild a
different compiler for every possible target, because the sysroot value
is set at configure time.

Oh.... bummer.  I'm using GCC 3.4.6.  Checking the docs on gcc.gnu.org
it looks like this newfangled --sysroot option you are describing was
added in GCC 4.1 :-/

Argh and double argh.

I guess I can't complain since they did implement essentially exactly
what I asked for... but I still can't use it.  Sigh.

Back to the drawing board I guess...  I have a thought which is a hack
but might be good enough.
