The gnu c++ compiler version 2.3.3 doesn't seem to be emitting code for the template
operator<< routine.  When I issue the command:
	g++ test.cc
I get the following complaint from the loader:
    ld: Undefined symbol 
       ___ls__FR7ostreamRt4Test1Zi 
    collect: /usr/bin/ld returned 2 exit status

Is there a compiler switch I'm missing?

I'm using gcc-2.3.3 on a SPARCstation(SunOS 4.1).
