   1 /* unified sys/types.h:
   2    start with sef's sysvi386 version.
   3    merge go32 version -- a few ifdefs.
   4    h8300hms, h8300xray, and sysvnecv70 disagree on the following types:
   5
   6    typedef int gid_t;
   7    typedef int uid_t;
   8    typedef int dev_t;
   9    typedef int ino_t;
  10    typedef int mode_t;
  11    typedef int caddr_t;
  12
  13    however, these aren't "reasonable" values, the sysvi386 ones make far
  14    more sense, and should work sufficiently well (in particular, h8300
  15    doesn't have a stat, and the necv70 doesn't matter.) -- eichin
