This reminds me of a question I had:  Should properties get propagated
to inline targets?  If I have this:

    lib foo : [ obj a : a.c <optimization>off ] b.c : <define>FOO ;

b.c gets compiled with FOO defined, but a.c doesn't.  I expected it to
and was surprised when it didn't.

I got .pdb files at least partially working.  If you want, I can try to
finish it up and submit a patch.
