can anybody tell me under what licenses are the above two libraries
released? a look at files under gcc-3.0/libstdc++-v3/src shows most
of them to be GPL.
Since almost every c++ program now links with libstdc++ (which has a
dependency on libgcc_s), does this mean that I cannot distribute
commercial software built with g++?

Did you notice the "Special Exception" statement in the license of
files in libstdc++-v3?
Also, please stop sending email with no return address so that it
looks like you are emailing from gnu.org. Given that the email header
displays:

It makes your employer, Sun Microsystems, look very incompetent about the
configuration of the email system and does not allow anyone to respond to
you.

They're all GPL + the run-time exception:
<quote>
In addition to the permissions in the GNU General Public
License, the Free Software Foundation gives you unlimited
permission to link the compiled version of this file into
combinations with other programs, and to distribute those
combinations without any restriction coming from the use of
this file. (The General Public License restrictions do apply
in other respects; for example, they cover modification of the
file, and distribution when not linked into a combine
executable.)
</quote>
If you find any source or header files installed as part of GCC, or
used in one of the libraries installed by GCC, that does not contain
this exception clause, please let us know, because it should be fixed.

I always wonder about macros and templates when I read this. The corresponding
exception phrase in Ada says:
-- As a special exception, if other files instantiate generics from this --
-- unit, or you link this unit with other files to produce an executable, --
-- this unit does not by itself cause the resulting executable to be --
-- covered by the GNU General Public License. This exception does not --
-- however invalidate any other reasons why the executable file might be --
-- covered by the GNU Public License. --
(instantiation of generics is the Ada equivalent of template expansion)
Neither seems to really fully address the issue of inlined procedures.

^^^^^^^^^^
I assume you meant proprietary? There is plenty of commercial Free Software
distributed under the GPL around!

The intent is to be GPL with the libgcc exception clause. Read each
file you may be interested in, and let us know if it isn't so covered.
I suspect they all are.
The exception clause for libgcc is currently worded as:
In addition to the permissions in the GNU General Public License, the
Free Software Foundation gives you unlimited permission to link the
compiled version of this file into combinations with other programs,
and to distribute those combinations without any restriction coming
from the use of this file. (The General Public License restrictions
do apply in other respects; for example, they cover modification of
the file, and distribution when not linked into a combine
executable.)
and the one for the C++ library reads as:
// As a special exception, you may use this file as part of a free software
// library without restriction. Specifically, if other files instantiate
// templates or use macros or inline functions from this file, or you compile
// this file and link it with other files to produce an executable, this
// file does not by itself cause the resulting executable to be covered by
// the GNU General Public License. This exception does not however
// invalidate any other reasons why the executable file might be covered by
// the GNU General Public License.
They were designed to be commercial software friendly.

No, it doesn't mean this.
