How do you sort out something like this:

config FOO
	bool "Foo"
	depends on (A && B) || C

Do you enable A and B, A, B and C or just C?

Bear in mind that A could be 'X86', 'M68K' or any other arch specific

I prefer the warning method because it prompts you to investigate what's
changed and sort out the problem by ensuring that the appropriate symbols
are also selected.  The automatic selection of dependencies method carries
the risk that it'll do the wrong thing with the above scenario.
