3 :			* COPYRIGHT (c) 1995 AT&T Bell Laboratories.
4 :			*
5 :			* This file contains definitions to hide a few OS dependencies. It
6 :			* should be portable across both UNIX and non-UNIX systems (unlike the
7 :			* UNIX specific "ml-unixdep.h" header file).
8 :			*
9 :			* GETPAGESIZE() return the machine's pagesize in bytes
10 :			* PATH_ARC_SEP the pathname arc separator character
11 :			* SYSCALL_RET_ERR this is set, if system calls typically
12 :			* return an error code status (unlike UNIX,
13 :			* where the global errno is used).
