+dnl Define a new AC_ARG_ENABLE like macro which handles invalid inputs
+dnl correctly.  The macro takes three arguments:
+dnl  1) the option name (used like --enable-option)
+dnl  2) the help string
+dnl  3) the default value (either yes or no)
+dnl
+dnl This macro also defines on variable in the form "option_enabled"
+dnl set to either "yes" or "no".

+    no)   $1_enabled=no ;;
+    *)    AC_MSG_ERROR([bad value ${enableval} for --enable-$1]) ;;
