Although it seems strange to run cygwin on top of wine,
doing so would make it possible to run a lot of build
scripts for windows apps unchanged, which would be
very handy in verifying that wine works properly
(see http://wiki.winehq.org/UnitTestSuites ).

The problem is, wine doesn't support the system attribute
on files well.  There's no convenient place to store that bit.
That means that installing cygwin on wine fails subtly;
/bin/cc doesn't get installed at all when you install gcc,
for example.
This problem is described in more detail at
http://bugs.winehq.org/show_bug.cgi?id=15679

Since cygwin special cases some file system that doesn't
support the system attribute, maybe it could do something
similar when running in Wine.   Or alternately, Wine
could notice the attempt to set the system bit on
a file that looks like a cygwin symlink, and create
instead a real unix symlink.  (Probably not a good idea,
offhand.)

Has anybody thought about this issue?

Thanks,
Dan
