net-nntp/pan-0.132 fails to build with gcc 4.3, due to missing #includes. This patch makes it compile and run without problems. A warning is generated for the use of the now-deprecated <ext/hash_set> header, but that's something that should be fixed either when it starts causing problems, or when upstream gets around to it.

FWIW, the upstream/pan bug, using a slightly different patch, is
applet in -r2, thanks.
