Casts are "abstract declarations".  This means that if you drop the
outer parens, there is exactly one place where a variable name (say,
`foo') could be inserted to make this a real declaration.  Above,
the only place would be:

	int *(*foo)()

So, this is "cast to ptr to function returning ptr to int".
