When FreeBSD evolved, it was primarily GCC that has been used
as the system compiler, so it became the standard. With Clang/LLVM
offering both evolution in compiler design and implementation, as
well as a licensing difference to GPL-based GCC, it was chosen
to be the current default.

I think PCC wasn't on the map yet at that time... ;-)

PCC seems to gain more attraction, primarily due to OpenBSD.
I'm not sure if this project is still alive, but I found this
statement by A. Magnusson:

	The big benefit of it (apart from that it's BSD licensed,
	for license geeks :-) is that it is fast, 5-10 times faster
	than gcc, while still producing reasonable code [...]
	it is also quite simple to port.
