No.  The use of the word "derived" in C++ is unrelated to its use in the
copyright/copyleft notion of "derivative work".  A derivative work results
when you modify the copyrighted program to produce a new program.  When you
use inheritance, you are writing a new program that just references the old
program, just as an ordinary program references a library routine.

Note that this answer assumes that libg++ was released under the GNU
*Library* Public License, not the regular GNU Public License.  Under the
regular GPL, linking a program with the library results in a derivative
work, so it has to be copylefted.
