Thanks. I know how hard it is to debug something without a reasonably 
test or fail. And this was easy to reproduce.

I've followed Vladimirs suggestion and it works.

But someone broke gcc.jam. It fails to add -L option to the linker to 
specify the library search path.
The follwing patch fixes this, though I'm not sure if I've put the 
option at the right place. 
I've also tried to add threading-support to gcc, but succeeded only in 
adding _REENTRANT to the complie flags. Is this the rigth way to it ?
Can someone point me on putting -pthread to the linker command ?

Yours,

Jürgen
