No, that's not what it means.  Here are some infoblurbs about C++:

It's a common misconception (according to Stallman) that "free" is the
opposite of "commercial".  You can write software that is both
commercial and free, by simply providing sources to your commercial
software.  Such commercial software may freely use any GPL library.

The GNU C++ library (libg++.a) is LGPL, meaning you must provide
objects (not sources) for your application.

The only parts of libg++ that is LGPL are the parts that are NOT
defined by the ANSI C++ standard (i.e. the GNU extensions).

Those parts of the C++ library that are NOT LGPL are duplicated in the
libraries libstdc++.a and libiostream.a.  You may use these two
libraries freely in your software, without invoking the LGPL.

If you do not wish to provide sources or objects for your
applications, you must restrict yourself to libsdtc++.a or
libiostream.a, and not use libg++.a.
