Hi Roman,
I tried to implement a "select at least one of these options" using the
following Kconfig snippet:
config A
bool "a"
config B
bool "b"
config C
bool
default y if A=n && B=n
select A
select B
"make *config" says
Warning! Found recursive dependency: A C A
Warning! Found recursive dependency: C A C B
and handles it a bit strange.
Yes, there is a limited recursion, but it's a finite recursion and I
don't know of any other way to express this in the current kconfig
language.

This sort of dependency would be better handled with another choice
option, but this is not really 2.6 material.

It's not really possible. You can show a comment if nothing is selected
and use a reasonable default.
