It seem to me the problem is in autoconf.h/fixdep, not in the Kconfig language. > This commit makes Kconfig error out if it finds a symbol suffixed with > '_MODULE'. I know you don't care, but I will voice my objection, for the record: Kconfig is used by projects other than the Linux kernel and some of them do not use the autoconf.h functionality. For such projects this restriction seems arbitrary and potentially backwards-incompatible.
