I haven't got the magic bullet of course, but since we do have a way
to make Win32-using programs work with just a relink, how about this
- Add the previously suggested CYGWIN option for syncing the Win32
working directory, with two settings: on and off. Default to on for
the moment. That would allow people like Daniel Colascione to switch
it off if they don't care about the resulting failures in cygutils and
- Implement the -lsynccwd scheme.
- Notify maintainers about the rebuild that's necessary if their
packages use Win32 APIs. Rebuild cygutils, git, and tcltk as soon as
- In a few months, switch the default to not sync, and hence allow
working directories to be deleted., and which point. Affected programs
that haven't been rebuilt could still be made to work by switching the
option back on.
