Actually, it was not a mistake.  I knew that I was breaking backwards
compatibility.  Putting this inside impure_ptr would have been very
difficult.  I thought I had a magical way of speeding up cygwin's
stat function but it turned out to be flawed.

We break compatibility with older DLLs all of the time.  For instance,
"I've" just added the signgam export and I'm in the process of exporting
sys_nerr and sys_errlist.

As soon as something is compiled which uses one of those
variables/functions, it will be unusable with older dlls.

It isn't.  If you've downloaded the latest package, requiring the latest
DLL is not an issue.

Right.  No one guarantees that we'll respond to every bug report.  We
eventually did respond to this one, though.  So be grateful for that.
We're all volunteers.  Who knows what other events were going on in our
lives when this urgent bug report surfaced?

The reason that Cygwin is "flaky" is that I'm trying to fix a pretty
serious problem in 1.3.2.  I have had zero time to devote to fixing the
flakiness this week, though.

And, *of course* we release versions that have unknown side effects.
You might as well say that we all need oxygen to survive.  If the side
effects were *known* then we wouldn't release them.

The usual counter to that is "You should do better testing" and I would
love to have a fully fleshed out test suite and someone to run the
tests.  I don't have any of that.  What I have is people who try out
cygwin snapshots.  If they report bugs in the snapshots, I try to fix
them.  When things seem relatively stable (which they are definitely not
right now) then I release a new DLL.

Consider it a rite of passage.  When Chuck reports a bug, I think "Hmm.
There must be a bug" and I investigate it.  Guess why that is?

When random cygwin mailing list person reports a bug and I am not
immediately familiar with it I usually put it in my queue to investigate
or I ask Corinna to look at it, if it is in her area of expertise.  We
have an incredible number of people reporting non-bugs, asking the same
question, making the same "suggestions".  So, bugs from unknown sources
don't get a lot of my attention.

FWIW, these days when I see email from Ralf, I put it in my priority

Also, I don't think that it is extremely clear that the libraries will
be disappearing or that the cygwin DLL is unofficial.  It's mentioned in
your readme but we all know how many people read that.

Also, since you include a modified version of the cygwin 1.3.2 DLL, I'm
not sure why you need versions of Chuck's packages.

...and the whole purpose of the "no new packages" is so that we can
work out a scheme to include X11 and KDE in cygwin setup.
