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

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

$ cat configure.ac; autoconf
AC_INIT(foo)
AC_ARG_ENABLE(foo, boo, , enable_foo=foo)
echo $enable_foo
AC_OUTPUT
$ ./configure
foo
$ ./configure --enable-foo
yes
$ ./configure --disable-foo
no
