Ok.

Can't we add this information? When you find a symbol, if it's through
a depends on or a select, you store the symbol, but mark it as
"referenced". When you find a symbol that is really defined through
config/menuconfig/choice, you store the symbol and mark it as
"defined" (or changed from "referenced" to "defined" if the symbol had
already been found). And then, at the end of the parsing, if there are
some remaining symbols marked "referenced", whose state has not been
changed to "defined", you warn about them.

Am I dreaming too much about kconfig ? :-)

Thanks!

Thomas
