egcs, warning patch for missing initializers in xsys-protos.h

["Kaveh R. Ghazi" <ghazi at caip dot rutgers dot edu>]

	The following patch gets the last couple of warnings from
gen-protos.c and removes 1350 warnings mainly of the form of missing
initializers in the generated file xsys-protos.h.

	Okay to install?

	* gen-protos.c (parse_fn_proto): Cast argument of ISALNUM to
	`unsigned char'.
	(main): Mark parameter `argc' with ATTRIBUTE_UNUSED.
	When generating output, initialize missing struct member to zero.
