A mount table approach along the lines of the cygdrive prefix handling
might not be such a bad thing, after all.  Something along these lines

  none /mnt cygdrive binary,posix=0,user 0 0
  none /unc uncdrive binary,posix=0 0 0

This would also fix the somewhat special feature that unc paths get the
same default flag treatment as cygdrive paths.
