Building shared library that uses libstdc++

[Lundell, Jens O.]

Thank you very much Alex, it worked. 
It would be nice if some of these common compiler switch combinations were
collected into a FAQ or something. It's not easy to correctly put all the
pieces together from the "GCC Command Options" page. Especially since some
of the information is in the wrong place, "-mimpure-text" is for example
described under AMD29K options instead of under SPARC options.

Thanks,

Jens
