There may be some confusion because what's distributed as libg++ by
the FSF is actually several libraries: libg++, libio, libiostream, 
and libstdc++.  These libraries are distributed with different 
licences.  Libg++ itself is under the GPL.

Libg++ proper contains generic classes for abstract data types like
strings, lists, queues, trees, hash tables, etc.  The STL (standard
template library) which is part of libstdc++ provides similar

I understand that using STL at this moment can be awkward due to g++'s
template instantiation mechanism.  There is an unofficial "repo" patch
(to gcc/g++) that helps.

In any case, I'm not suggesting that libg++ be removed, just that the
default C++ compiler front end be "c++" instead of "g++" so that
libg++ is not linked in to peoples executables inadvertantly.  Those
who use libg++ can either add -lg++ or link with g++.
