Note that your issues have very little to do with the *development* of 
libstdc++. Actually, I would say have little to do also with the *use* 
of GCC as GCC, these are generic Unix / Linux questions, thus I'm not 
even sure about recommending gcc-help instead.

ldd on the executable, for example.

LD_LIBRARY_PATH, for example.
