AS_PREPARE is used in the prolog of the configure script; _AS_PREPARE is
used in the prolog of config.status.
The problem is that we want the configure script's initialization to be
emitted in the right diversion, and that's why we cannot just use
Or are you saying that AS_PREPARE is totally useless? I'm not sure we
would not miss anything in the prolog of the configure script if
AS_PREPARE was not used.
