[980307]: Warning patches #5/5 - the rest...

[Manfred Hollstein]

This patch corrects:

  1. function `compute_preds_succs' actually doesn't return anything,
     although declared as int
  2. casts a char value used as an array index explicitly to int

gcc/ChangeLog:

Sun Mar  8 17:06:02 1998  Manfred Hollstein  <manfred@s-direktnet.de>

	* basic-block.h (compute_preds_succs): Change return type in
	prototype to void.
	* flow.c (compute_preds_succs): Likewise in function definition.

	* regmove.c (find_matches): Explicitly cast char used as array index to int.
