This patch include various fixes to NBSD includes. - unistd.h: Avoid different linkages on non-_NETBSD_SOURCE compilation; - stdlib.h: remove devname declaration. - sys/select.h: Add _MINIX specific flags. - limits.h: Add SYMLOOP_MAX and SYMLINK_MAX - time.h: Fix CLOCKS_PER_SEC and remove BSD's timer_t, as it confuses minix own specific timers. - utmp.h: Set Minix-specific paths and use Minix utmp format. - param.h: Do not set BSD4_4, as this mostly means sa_len in struct sock_addr. - arch/i386/include/param.h: include <machine/vmparam.h> to add PAGE_SIZE and related macros, defined round_page() and trunc_page() for minix compatibility. - dirent.h: remove DIRBLKSIZ and fix d_ino/d_fileno. - sys/dir.h: ADD from existing includes and edit include conditions. - sys/dirent.h: include <minix/dirent.h>, fix d_ino/d_fileno. - sys/fd_set.h: set default FD_SETSIZE at __MINIX_OPENMAX, as the default NetBSD value is too big and cause vfs to return an error. - sys/cdefs.h: Always include <minix/ansi.h> - minix/paths.h: Add Minix-specific paths. - minix/dirent.h: ADD, keep only "direct" and "flex"definitions. - minix/types.h: include <minix/ansi.h> - sys/Makefile: add sys/dirent.h and statfs.h (forgot!) - minix/Makefile: add minix/dirent.h nbsd_include/minix-port.patch updated accordingly.

* Note: The V7 format directory entries used under Minix must be transformed
|
|
* into a struct dirent with a d_name of at least 15 characters. Given that
|
|
* we have to transform V7 entries anyhow it is little trouble to let the
|
|
* routines understand the so-called "flex" directory format too.
