reserved fields in stat structure

[haceaton@aplcomm.jhuapl.edu (Harry Eaton)]

The stat structure in the stat.h include files has some "reserved fields" i.e.

...
        time_t  st_ctime;
        short   st_attr;
#ifdef __MINT__
        short   res1;           /* reserved for future kernel use */
        long    res2[2];
#endif
...

Are these reserved for a known purpose at this time?  I'm interested in
using one of the long words to return data for the size of resource forks
of Macintosh files (for MacMiNT).  Is this reasonable?  How does one go
about getting the MiNT developers ok for such things?
