I just applied a patch which allows to run Cygwin applications, even if
the Cygwin DLL is installed into the root directory of a drive or
network path.

Note that certain paths still have to match the expectations.  For
instance, if D: is the root dir, the fstab, passwd and group files are
still searched in /etc, which is D:\etc.
Also the /usr/bin and /usr/lib default mount points will invariably
point to D:\bin and D:\lib, unless there's a /etc/fstab file which
changes them per the user's guide.
