text: /* 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
