  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
