I was really curious about the implications of that so had some further
questions, but I am going to drop those questions because they are a
distraction from the principal point I want to make.

In sum, if any Cygwin developer here feels moved to help debug Wine so
that the Cygwin install works properly on it, the best thing you could
do would be to follow the steps I detailed at at
<http://bugs.winehq.org/show_bug.cgi?id=24018>) with Wine-1.6-rc4
patched with Andrey Turkin's patch, and with Cygwin updated with the
recent snapshot cygwin1.dll that contains the fork fix.  Then run that
exact same setup.exe procedure (with the fork fix applied in the same
way) on Microsoft Windows.  Such direct comparisons between Wine and
Microsoft Windows results would be a great help in figuring out which
of the many error messages that show up in a fresh install of Cygwin
on Wine should actually be of concern to Wine developers.  (I cannot
do such comparisons myself because I don't have ready access to
Microsoft Windows, i.e., I have been running Linux since 1996 and my
only Windows experience is running MinGW/MSYS on Wine off and on as a
build and test platform for software for the last couple of years).
