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.
