1c614b9e79 AC_REQUIRE and AC_DEFUN_ONCE don't work properly together. This 
caused strange messages about AC_ARG_PROGRAM.
Reported by Jim Meyering.
* acgeneral.m4 (AC_DEFUN_ONCE): Fix the indirection to
m4_defun_once.
* m4sugar.m4 (m4_defun_once): Also define
`m4_location(MACRO-NAME)'.  s/ac_warn/m4_warn/.
Use `m4_defn' to read `m4_location'.
* tests/base.at (AC_REQUIRE & AC_DEFUN_ONCE): Two new tests.
