I am not a lawyer.  From

http://www.gnu.org/licenses/gcc-exception-faq.html

I use a proprietary compiler toolchain without any parts of GCC to
compile my program, and link it with libstdc++. My program itself does
not include any runtime library code the same way that GCC-compiled
programs include libgcc. Can I still take advantage of the exception?

    Yes. While combining libgcc with GCC-compiled object code is
probably the most common way the exception is used, neither the GPL
nor the GCC Runtime Library Exception distinguish between static
linking, dynamic linking, and other methods for combining code in
their conditions. The same permissions are available to you, under the
same terms, no matter which method you use.

It indicates both libstdc++.a and libstdc++.so are covered by GPLv3
run-time exception.
