alias fixes for Stunos

[Jeffrey A Law <law at cygnus dot com>]

The stunos compilers choke if you declare a function as static, but do not
define the function as static.


This patch fixes the definition of a few functions in alias.c to make the
stunos compiler happy.


	* alias.c (fixed_scalar_and_varying_struct_p): Add "static" to
	function definition.
	(aliases_everything_p, write_dependence_p):Likewise.
