Going through the web archive to see what I missed, I see David Wheeler's
post, which he emailed the gist of to me earlier:

It's in. Now that the website's back up... :)

As I pointed out earlier, I moved several files (and would like to move more,
but functionality takes priority over cleanups for the moment). This is
going to confuse the HECK out of cvs...

I'm happy to maintain my fork for a longish time, but I'm still amazed anybody
thinks I know what I'm doing. It's out there for anybody to use and I'll do
the best I can with it, but other people "checking for completely insane" is
a good idea, yes. :)

Getting Fabrice to spend time on tcc again would be enough of a coup that I
wouldn't quibble about how. That said, extracting multi-file patches from an
active CVS repository is a serious pain.

I also have a "breaktcc.c" somebody sent me that tcc segfaults trying to
compile. (Attached.) Haven't had a chance to look at it yet...
I think I've now gone through everything linked from the wikipedia tcc entry
and merged it. Still haven't tackled the TODO list in the source.

I'm reviewing that patch. I'm hoping there's a sane way to do it with less
extra function parameters sprinkled everywhere, but I only had time today to
read about 8 more pages of my big 205 page printout of tcc.c I made last
year. (In a 3-ring binder and everything.)

Release early, release often. A release is just a known checkpoint at which
it worked for the person releasing it and it had a finite set of bugs.
(Releases aren't moving targets the way source control is. They don't
spontaneously regress. This is a good thing.)
> Comments welcome. Does this make sense?
I have no objections, of course. :)
I point out that mercurial is designed to be distributed. Anybody who wants
to clone my repository and do their own changes is welcome to, although I
have yet to master this whole "pulling" thing and am likely to just cherry
pick patches for the moment. Patches on the list is good, people poke me if
they stay on my "to review" list for too long... :)
