This is strange.  I never knew that the main symbol was required for
shared libs.  Maybe that's OS X only...

... anyway, it seems your c++ (which is g++, right?) doesn't add libstdc++
which should define those symbols.  Repeat the above c++ link command
again, but add "-v -Q" to the arguments, and look how the linker is
acutally called.  Somewhere there should be the libstdc++ llibrary added.
