/dev is a bastard directory.  If it not exists on the filesystem, it is
faked within Cygwin, but then it is a read-only filesystem.  If it exists
on the filesystem, the device entries are faked by Cygwin, but you can
also add your own entries in /dev.

The above happens when /dev doesn't exist on the filesystem.  I didn't
get this error in my three test installations.  Usually /dev is generated
by the 000-cygwin-post-install.sh postinstall script, since it also
has to create the /dev/smh and /dev/mqueue subdirs.  I don't know why
it failed for you, though.
