/* unified sys/types.h:
   start with sef's sysvi386 version.
   merge go32 version -- a few ifdefs.
   h8300hms, h8300xray, and sysvnecv70 disagree on the following types:

   typedef int gid_t;
   typedef int uid_t;
   typedef int dev_t;
   typedef int ino_t;
   typedef int mode_t;
   typedef int caddr_t;

   however, these aren't "reasonable" values, the sysvi386 ones make far
   more sense, and should work sufficiently well (in particular, h8300
   doesn't have a stat, and the necv70 doesn't matter.) -- eichin
