Did you compile with gpp (instead of gcc)?  If you compile with gcc, you 
need to put -lstdcxx at the end of the link command line, to have the 
linker look in the library of C++ standard classes; gpp does that for you 
automatically.

What CC?  What version?  What Unix?

Each compiler has its own list of issues wrt the C++ standard.  None of 
them supports the latest standard 100%.  So comparison with other 
compilers are not always meaningful.
