Thanks, Kostik, for the fast response.
The error isn't so clear to me, sorry. I thought libstdc++.a is the
static library and it is taken to be referenced/compiled into a shared
object created by the application I try to compile.

I'm much more confused now, since I thought the last time I compiled
that piece of software, I never got any error like that. Well, clang
fails with some obscure errors on the code itself and I'm unwilling to
correct them, I'll try the legacy gcc 4.2.1 and will report what's
happening.

Thank you very much,

Oliver
