I'm not an expert on C++, so I can't give you all the gory details, but I do
know that libgpp.a is to C++ as libc.a is to C.  It defines everything that
you use in your program that is C++ specific, like cin, cout, all the streams
and classes, etc.  Essentially, if it's in <iostream.h>, you need libgpp.a.

An alternative, if you are concerned about the GNU General Public
License, is to use only libiostream.a, which defines the basic C++ streams
but not most of the standard classes.  I'm not an expert on the differences;
there is a section in the FAQ which deals with this.  Note that if you want
to use libiostream _instead_ of libgpp, you can't use 'gxx' to compile.

P.S.:  I'm forwarding this to the list as well; anybody who knows more feel
free to correct me.  :)
