They're nice, but if we use them, we must also use bleeding-edge
Automake (latest git on maint branch, or Automake 1.11.3 or later when
1.11.3 comes out) when cutting releases, so that the resulting
makefiles are POSIX-compliant.  Otherwise, Bison won't build on
systems like HP NonStop whose 'make' implementations conform to POSIX
but do not support nested variables like GNU make does.  Please see
<http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9928>.

It may be simplest to wait until Automake 1.11.3 comes out before
applying that patch.  I don't think this will be long.
