[boost] [config] Detecting exception handling in g++

Dear Boosters,

The following patch to boost/config/compiler/gcc.hpp enables automatic
detection if exception handling is enabled or not in g++.  I have
confirmed at least g++ 2.95.2 and 3.2 on Linux define __EXCEPTIONS by
default and undefine it with -fno-exceptions.  Please apply this patch
if there's no problem.

Best regards,
