/* 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
