varargs question

[Brian Renaud]

I am writing a function which, ideally, would take an optional
argument which would be a pointer to a function which returns a
pointer to a char.  I am using a non-ansi <varargs.h> type compiler.
My code looks something like:

	...
	char	*(*func)();	/* local variable to hold pointer */
	...
	func = va_arg(ap, char *(*)());

Unfortunately, va_arg turns the cast into something like:

	(char *(*)() *) ...

instead of the desired:

	(char *(**)() ) ...

Am I (quite likely) just making a dumb error here?  If not, is there
some portable workaround to deal with this?
