Here's a starting point for an update for pcc to 1.1.0. It builds with -fno-common and depends on the attached new port of pcc-libs.
On amd64, it compiles a working hello world successfully (with -fPIC)
and produces a usable cat binary with
cd /usr/src/bin/cat && make CC=pcc DEBUG=-fpic STATIC=
I would probably still go with 1.0.0 and -fcommon as in my previous
mail, but if anyone is interested in finishing this up, I think it's
not too far off track.
