If you don't use any of the classes that the C++ library provides, then 
your program does NOT link in any modules from the C++ library.  To make 
sure you don't link in something from the libgpp.a library (which alone 
is under the GNU license), link your program like this:

	gcc -o myprog file1.o file2.o ... -lstdcxx -liostream

(here file1.o etc. are your object files and myprog is the name of the 
program you are producing).  This tells gcc to only search the libraries 
which are totally free.  If gcc doesn't complain about unresolved 
externals, you are safe.
