23/* unified sys/types.h:
24 start with sef's sysvi386 version.
25 merge go32 version -- a few ifdefs.
26 h8300hms, h8300xray, and sysvnecv70 disagree on the following types:
27
28 typedef int gid_t;
29 typedef int uid_t;
30 typedef int dev_t;
31 typedef int ino_t;
32 typedef int mode_t;
33 typedef int caddr_t;
34
35 however, these aren't "reasonable" values, the sysvi386 ones make far
36 more sense, and should work sufficiently well (in particular, h8300
37 doesn't have a stat, and the necv70 doesn't matter.) -- eichin
