Hmm... yes, looks like it (tested with GCC-2.95.2 on Linux).  I'm
surprised.  I was pretty certain that if you did linking and
compilation in one go, gcc recognized that the source file(s) are in
C++, so the C++ runtime should be linked in automatically.  I.e. I thought

	gcc -o hello hello.cpp

worked.  Turns out it doesn't ;-(

Time for a memory reboot, it seems.
