Patch to fix SunOS4 bootstrap failure

[Kaveh R. Ghazi]

	When building stage1 on SunOS4 using cc, I get the following
bootstrap error:

Here's a patch, okay to install?

	* haifa-sched.c (sched_analyze): Rename local variable `region' to
	avoid conflicts with typedef struct `region' at the top level scope.
