I agree with Jim more on both counts.  I have started doing what Jim is
thinking off not for POSIX but ... that is for a completely different
purpose and better not elaborated upon here.

When I first looked at the port in December, I fixed the times.cc bug.  I
posted to this group, but the mail never made it.  Then I posted it to
cygnus and didnt get any reply either.

For interest, here is my copy of first posting that failed to appear after
three attempts.  I have progressed since then, but at this stage, I am not
ready to make any annoucnements.

If there is sufficient interest, I will, at a later date make my stuff
available -- terms etc yet to be resolved as I am not as conversant as the
pundits here on GPL and LGPL.

One way I know how many make their money	1) make a limited edition for
freely available, 2) get assistance for the community at large to improve
it under names like 'beta-testers' or 'public-domain'; 3) wait till enough
users are hooked on it; 4) then charge heaps for your full functional
version that you developed in parallel!

No one can then prove that the full functional version is a derivative of
the free version already in public domain :)

Cheers
