	I am just getting it together as far as switching over to
	ANSI C, and am having a small problem, which I believe is 	
	a bug in gcc, though maybe I am just doing something wrong:
	I am using gcc version 2.2.2

	Here is a function definition:

XtEventHandler
dbSelectRecord(Widget w, FormRecPtr f, XButtonEvent *ev, Boolean *flag)
{
	...
}

	and later on in the same source file, I call XtAddEventHandler as :

XtAddEventHandler (f->selectionText, ButtonPressMask, 
                   FALSE, dbSelectRecord, f);

	My confusion is that I get a warning saying that dbSelectRecord
	is not the right kind of arg for this function.  If I cast it
	to (XtEventHandler)dbSelectRecord,  then all is fine.

	Seems to me like this ain't right.
	Any comments would be quite appreciated,
