to require and older version of tcl/tk. Given that the latest version
(called 2.2, as opposed to 2.0 that we have) is timestamped November
'95, we may not have much hope. :(

lcc is a production compiler with a hand crafted lexical analyzer and a
hand-coded recursive decent parser. The lexer and parser code is well
written and very easy to read (and learn from :-)).
lcc compiles much faster than FreeBSD's stock [gcc] compiler. However, it
does not under stand FreeBSD's "long long" data type.

Some of us were playing with it at school... so I made a port of it.
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)

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.
