This is something I hacked together a while ago vs. 4.3.2 when I discovered
you couldn't add -lsupc++ to LIBSTDCXX_STATIC because it counts as a single
word in argv. (I later decided I didn't need to do this anyway, can't
remember why I thought I needed to.) It's unconditional and would need to be
made so but I think it would be the basis of a solution. Franz, you could
attach it to the bug report when you file it, it might be useful to somebody.
