 Good day,

	I'm using gcc on a sun4(4/75).
	I'd like to know how to determine the number of bytes passed to a 
function.  I've got a varargs function and would like to determine from 
within the function how many arguments were passed.  Also I'd be interested 
in any information on the call convention of gcc, i.e. what a argument stack 
looks like, what does gcc do with passed structures, what is the size limit 
of data passed on the stack.

	Thanks.
