Point taken. I've just committed to CVS a little modification
that may help in these cases; Allin, feel free to revert it if
there's anything wrong with it, but I tested it a little and
there seem to be no ill side effects (famous last words).
Basically, the keyword "null" is now a valid value for pointers,
and can be specified as a default value.
Nothing wrong with it, but actually this was already supported.
The (useful) sample script you gave runs fine without the change
to check_function_args(). The case is handled by the first
condition:
if ((fp->flags & ARG_OPTIONAL) &&
arg->type == GRETL_TYPE_NONE) {
Allin.
