I like it.  Patch installed, using that wording.

Empirically, the list archives document 4.2.x and 4.3.2 as broken:
http://lists.gnu.org/archive/html/autoconf/2007-04/msg00086.html

Cygwin ships with zsh 4.3.4 which works.  Therefore, I changed 4.X.Y to 4.3.4 
(it wasn't worth my hassle of looking up whether 4.3.3 was also broken).
