With a circular dependancy like this, I'd actually recommend building the
two together into a single module file. There doesn't seem to be any
utility in having them in separate files at all.
However, should you wish to have a module depend on another module, you
should use the MODULE_DEPEND macro in your sources.
MODULE_DEPEND(this, other, min, preferred, max)
this the name of this module
other the name of the required module
min minimum version of the other module acceptable
preferred preferred version of the other module
max highest version of the module acceptable
