43703ea9aa * m4sugar.m4 (m4_location): When using its value, don't use 
`m4_defn', since m4_location is not a variable, it's a macro which
expands to __file__:__line__.
* tests/m4sugar.at (m4_warn): New test.

7e4f776a09 * autoconf.m4: Instead of reactivating the macros before reading 
Autoconf's file, do it afterwards, so that Autoconf promotes the
right use, but users still can use the old names.
Of course this revealed numerous non updated uses of old macros in
Autoconf's files.  Adjust them.
But for the time being, keep `define' alive for Autoconf.

1c614b9e79 AC_REQUIRE and AC_DEFUN_ONCE don't work properly together. This 
caused strange messages about AC_ARG_PROGRAM.
Reported by Jim Meyering.

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'.

3f580f38ab * m4sh.m4 (_AS_UNSET_PREPARE): New macro, eved from
