Your problem seems to me to be simple of solution.  That is unless I misread
your article.  Why don't you use preprocessor defines in your source files,
and test for them in your include files.  Here is an example:

---------- source.c ---------
#define BIT_to_DBMS
#include <header.h>

...
-----------------------------
---------- major.c ----------
#define SYSTEM_ACCESS
#include <header.h>

...
-----------------------------
--------- header.h ----------
#ifdef BIT_to_DBMS
...
#endif /* BIT_to_DBMS */

#ifdef SYSTEM_ACCESS
...
#endif /* SYSTEM_ACCESS */

#ifdef DBMS_to_BIT
...
#endif /* DBMS_to_BIT */
-----------------------------

If this is NOT a solution to your problem, then I DON'T understand it.
