I took gcc1030b.zip and its companion gpp1030b.zip as an example: libgcc
is under <base>/lib/gcc/djgpp/10, whereas libssp and libstdc++ are under
<base>/lib, and my version handles both.

Yes, that's an advantage.

Yes, that's another advantage.

The only downside to your patch is that older gcc versions have a problem
handling -T on their command line, which is why I had gone back.  I don't
have a solution for that, buit I honestly haven't tried very much.

Eli, DJ: What do you guys think?
