AX_* is sort of a reserved namespace as the large autoconf-archive
project utilizes it everywhere.  maybe pick a different prefix ?

Sure, any suggestion?

+        [AC_ARG_ENABLE([$1], [$2],[enable_$1=$enablearg],[$3])])

this 3rd arg is redundant.  that's pretty much what autoconf already
does.  i would just omit it.

$ cat; autoconf
AC_ARG_ENABLE(foo, boo, , enable_foo=foo)
echo $enable_foo
$ ./configure
$ ./configure --enable-foo
$ ./configure --disable-foo

Ah, cool. Will do. Hadn't realized that I could just omit an arg.

In that case, it may be better to just use that pattern in
(remove the arg) instead of defining a new macro.
