According to Ralf Wildenhues on 3/24/2008 5:43 AM:

Bah.  That should be m4_ifdef, not m4_if.

|> ~  [m4_define([_$0_text], [$1]m4_defn([_$0_text]))],
|> ~  [m4_builtin([m4wrap],
|> ~    [arg1(m4_defn([_$0_text])m4_undefine([_$0_text]))])dnl
|> m4_define([_$0_text], [$1])])])dnl
|
| This isn't sufficient

With the typo corrected, I get no difference on your simple example.

| (and also, arg1 is not namespace-clean):

True, but it's easy enough to change (and it is for a workaround, not part
of autoconf proper).
