The module is 8.0 and the requirement is 8.0
but since they use different defines it wont work.

It is really very simple

#define	A 8
#define B 8
#if A == B_PROVIDED
/* OK */
#else
#warning ""
#endif

The code should emit a warning if version A and B are not the same.
They are the same, but the warning will still occur,
since there is no definition of B_PROVIDED.
