c1b1010ad0 Bootstrap pgcc-current using -O instead of -O2 (for safety reasons, I don't
want higher optimization levels result in unsafer binaries).

Fix bug, that causes core dumps when using higher optimization levels
than -O2.

Results with dhrystone 2.1 (1000000 loops):
	stock cc (2.7.2.1 from current)	:	136k	(136xxx)
	pgcc-current with -O2		:	138k
	pgcc-current with -O6		:	172k

And no coredump anymore. Reason for coredump:
With -O3 cc1 does an register-to-register-copy optimization and it tries
to write some debugging information about what it is doing into a file
that does not exist unless you have instructed cc1 to dump all its
information about its internal state. (From: Sascha Blank)

BTW:	PLIST is really coming soon, it's on my todo list ;-)
BTW2:	Is Sascha already in the contributors list ? Have to go to work now.

9a84e6bfb5 pgcc-current is a developer release of gcc 2.7.2 with pentium
optimizations. The motivation to make a separate pgcc port is, to
provide two versions, an official release, which is missing the
leading edge of developement and an interesting current version,
which fixes some things and might breake (or not) others.

Fact is, that one is able to compile and run a complete FreeBSD-current
kernel without trouble and so closes 2 PR's.
