Hi,

It seems recent versions of setup-x86.exe exit before the installation is
complete. Without the --no-admin option, the main installation is run as a
child process, and the parent doesn't wait for the child to complete. This
can cause a bit of a problem for other installers that install Cygwin (as
when setup.exe exits, Cygwin isn't installed).

Is something like the attached patch appropriate? It just waits for the
child process before exiting.

Cheers,
Jon
