What is this obsession with replying 'Don't forget the inclusion guard'???
It's old hat. My secnario has this in place.

My problem is one module is creating a dependancy on another module only
because the first module wants to use one single #define in the second
module.

The application is a large one, backed up by an overly sophisticated build
system, which would mean if I want to pick up module 2, I pick up all of it:
it all gets compiled. (And yes, I know: it won't get linked in!).

So the question is: is it normal practise to create intermodule dependancies
for trivial reasons?
