Re: bug with dlpreopening c++ modules (shared objects)

Hi Ralf,

I attached the output of `make all' - there's not much before the
failing libtool command.

That's interesting. What else can I try / post to isolate this?
I tried the latest version of libtool and could reproduce it - that's
why I posted this here =).
The libstdc++ version is from a vanilla gcc 4.1.2, libstdc++.so.6.0.8 .

Cheers,
Christian
