As explained in the FAQ, the standard C++ library, including iostreams 
and STL, do not have the GPL applied to them unless you compile the code 
with a compiler other than gcc/DJGPP.  Code compiled with gcc can be 
distributed in binary form only if you like.

libgpp is covered by the GPL, so if that's a problem don't use it (better 
to use STL anyways).
