:	I think your VOID definition is broken.  In the file
:exec/interrupts.h is the structure:
:
:struct Interrupt {
:	struct Node	is_Node;
:	APTR		is_Data;
:	VOID		(*is_Code)();
:};

	That means 'pointer to function returning nothing'

:	Then, later on, when I try and do this:
:
:foo ()
:{
:	extern long	bar();
:
:	interrupt.is_Code	= (VOID) bar;
:}
:
:	...my compiler throws up.  Something about an invalid use of the
:'void' declaration.  I have Manx 3.4b.

	You are attempting to cast a function returning a long into... nothing,
which certainly does not match a function returning void.  This is what you
want:

	interrupt.is_Code = (void (*)())bar;

	Casting bar into a function returning nothing.
