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.

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.

package building.
names, e.g., "m3build-4" and "m3build-4.0". This makes it possible for
ports that depend on this one to require a specific version. Since the
shared libraries have been moved into a separate port, their version
numbers can no longer be used for that purpose.

version of CVSup.

necessary to make the SOCKS library work with Modula-3's multithreaded

the new "modula-3-lib" port. The split allows one to save a lot of
disk space by installing only the shared libraries needed for executing
programs. The full "modula-3" port is needed only if you want to
compile programs as well.
"modula-3-lib". It installs only the shared libraries needed for
executing Modula-3 programs. This saves a lot of disk space for
people who need to run Modula-3 programs but don't need to build
them. The original "modula-3" port now depends on this one, and
uses it to install the compiler and the rest of the development
system.
Also, everything is now built with optimization. I have been
testing this for at least a month, and haven't seen any problems
from it. It makes the libraries and executables substantially
smaller.
This new port also includes some hooks that will make SOCKS support
possible in the near future.

no problem with redistributing the original archive as long as we put no
restriction.)
all the COMMENTs! No package names, no version numbers, no "this is
absolutix-3.1.2" type comments that have zero information contents.
Now, without any bad examples to follow, nobody has an excuse to import
a port with those kind of comments. :)
Phew! 238 ports modified!

Could someone do this for me? Or tell me how?)

copies taken from /usr/src/contrib did not have their execute bits

Use new custom distfiles which are MUCH smaller than the ones from
DEC.
Use the gcc-2.7.2.1 sources on the system if they are found in
/usr/src/contrib, to avoid having to fetch that distfile.
Use an existing Modula-3 compiler to bootstrap the new one, if
there happens to be one installed on the system. Again, this
eliminates the need to fetch one of the distfiles.
Update the built-in thread-safe malloc to the latest version of
phkmalloc.

Fine, then. Let's get on with it. Reduce shared library version numbers!
Uh, Sir, with all due respect ...
DO YOU HEAR ME??? REDUCE SHARED LIBRARY VERSION NUMBERS!!!
Reducing shared library version numbers! ... <*whirr click*> Done!
All right, soldier, let's get the hell out of here... Soldier? ... Soldier??
First, change the port so that it builds a much smaller subset of
the SRC distribution. This eliminates the enormous swap space
requirements of the earlier port, greatly reduces the footprint of
the installed tree, and cuts the size of the package in half.
Second, include many important new patches. Among them is a slightly
modified version of phkmalloc that is thread-safe for Modula-3.
It eradicates some rare and baffling core dumps that cropped up
from time to time in the previous version of the port. The Modula-3
runtime itself is careful to use mutual exclusion around calls to
malloc. But there remained some sneaky backdoor paths into it from
external libraries.
Confession: In the original version of the Modula-3 port, I used
a major version number of 353 for the shared libraries, to correspond
with the SRC version number 3.5.3. That was a dumb move -- I should
have used 1. The current update is incompatible at the shared
library level, requiring me to increment the major version number
to 354, even though this is still based on SRC release 3.5.3. This
is bound to confuse some folks, unfortunately. I weighed a number
of alternatives, such as (a) cheating and going back to 1, and (b)
using a 4-digit major version such as 3531. But in the end I
decided that 354 would be the best solution, even though it's
confusing.

[The rush to 5.003 couldn't integrate this, so here it is]
The following is a patch for perltrap.pod, from 5.003 (also 5.002).
It integrates the latest version of my simple 425traps
document. 425traps demonstrated, with examples, all of the traps
which have been discovered and sent to me, which have bitten
folks making the transition from perl4 to perl5. It also gave
an example for each one, including all of the existing perl4
traps in perltrap.pod.
As always, if you discover something that isn't documented in
one form or another in here, and isn't an official (or at least
reported) bug, drop me a line with it. Also, when or if any
of these is ever formally declared a bug, I'll take it out.

only extract in that case.
While I'm here, make expect and expectk link with shared tcl/tk libs.
expectk used to be a 1/2 MB binary! (now it's 136KB)
I'd also rather change `-g' to whatever CFLAGS defined in
/etc/make.conf, but the author of expect has an explicit comment in
the Makefile about him not trusting compilers' optimization. Well,
if you say so.

it's usable. Plus, invoking global ctors when loading C++
object files now works; it didn't with the old incremental
loading.
before) and cvs still sent an empty log! :<
Anyway, what I was trying to say in the commit messages of patch-[ab] was
to run ldconfig right after installation of the shared libraries, so that
they can be found by subsequent runs of shared binaries.
Also, take ldconfig out of this Makefile's post-install rule.
