Some versions of SUN's cc have a bug that causes them to complain about
a redeclared identifier when you use a function declaration that takes a
struct with a FAM and this struct has only been declared but not yet
defined.

IOW, this will fail:
	struct foo;

	void bar(struct foo *);

	struct foo {
		int v;
		long *a[];
	};

	void bar(struct foo *foo) {} // SUN cc bug strikes here

So when we detect a SUN cc, we use an array size of 1 to workaround that
bug.

Guido, could you please test this patch?

I have no clue which versions of SUN's cc are affected, so I simply enabled
the workaround for all versions. Someone with more knowledge about that
should probably limit the check to only do that for the broken versions.
