The version at http://pcc.ludd.ltu.se is much more modern than the
original PCC. Among other improvement, it has a graph-coloring
register allocator.


The BSD license of PCC is nice, but the compiler is also *much*
faster than GCC and still produces acceptable code. I use it as
my default C compiler since a few weeks and must say that I am
quite impressed with it.
