http://gcc.gnu.org/PR44647 requests that std::new_handler  and
std::bad_alloc be put in separate files as this helps reduce code size
for embedded code linking to libstdc++.a.  I think the request is
reasonable so I plan to commit the attached patch to trunk unless I
hear objections.

        PR libstdc++/44647
        * libsupc++/Makefile.am (sources): Add bad_alloc.cc.
        * libsupc++/Makefile.in: Regenerate.
        * libsupc++/new_handler.cc (bad_alloc): Move to ...
        * libsupc++/bad_alloc.cc (bad_alloc): * New.

Tested x86_64/Linux

Indeed, let's go ahead with this Jon. Minor nit: please fix the list of
Copyright years in the new file to just 2010.

Thanks,
Paolo.

OK, thanks.   I'm always confused by that so will try to remember in
future:  the new file contains old code,  and now it looks as though
the bad_alloc definition was not copyrighted prior to 2010 ... which I
find odd.

The rule I always followed is that a new file has only the Copyright
year of the current year. Otherwise, if each specific bit of content
counts one would have to track back the year each appeared in the
repository or just guess (often wrongly) and add also years predating
its existence. That said, I have no problem with changing the rules I
followed so far...

Paolo.
