not to belabor this, but what does it mean when the two dependencies
are mutually exclusive, as in the example i provided:
-----------------------
config MCA
bool "MCA support"
depends on !(X86_VISWS || X86_VOYAGER)
help
MicroChannel Architecture is found in some IBM PS/2 machines and
laptops. It is a bus system similar to PCI or ISA. See
<file:Documentation/mca.txt> (and especially the web page given
there) before attempting to build an MCA bus kernel.
config MCA
depends on X86_VOYAGER
default y if X86_VOYAGER
---------------------
the two options X86_VISWS and X86_VOYAGER are simple "bool"s
representing the (radio-box) subarchitecture type.
the first seems to represent a dependency of *neither* of those
two listed options, while the second config *depends* on one of
them.
how exactly do you reconcile what looks like contradictory
dependencies for the same config entry?

wondering just how badly he's embarrassing himself by now ...
