Well, what about explicit exporting these symbols when building
libstdc++? Or may be it is better to include a separate module into
libstdc++ which will define these symbols and to treat them as extern in 
other modules (the last variant needs a little change in code
generation,
the first variant does not). It seems this can solve the problem. Are
there
exist other symbols with such properties?
