Unfortunately, this is an idea that has already been discussed
a couple of years ago, and people felt that this was not the
intent of that attribute. See:

   http://www.cygwin.com/ml/gdb-patches/2005-11/msg00380.html

I haven't followed any development on the DWARF3 side whether
something more appropriate has been introduced for that purpose.

What compiler are you using? Do you have any control on what
your compiler does? Perhaps you can add an extra symbol like
we do with the Ada compiler? Just some thoughts...
