I just wanted to add an std::priority_queue usage example in the documentations,
since it's not obvious when you don't know how tu use it.
Since there isn't an "html" target in the root Makefile of gcc i didn't check
for validity of the patch, but i think it's ok.
$ uuencode priority_queue-3.4.1.patch.uu < priority_queue-3.4.1.patch
