[src/trunk]: src/sys/arch/acorn26/stand/lib Add support for LIBSA_NO_FS_CLOSE...

[bjh21 <bjh21%NetBSD.org@localhost>]

details:   https://anonhg.NetBSD.org/src/rev/ad8b758e2d27
branches:  trunk
changeset: 531889:ad8b758e2d27
user:      bjh21 <bjh21%NetBSD.org@localhost>
date:      Tue May 28 14:38:55 2002 +0000

description:
Add support for LIBSA_NO_FS_CLOSE, LIBSA_NO_FS_WRITE, LIBSA_NO_FS_SEEK and
LIBSA_NO_TWIDDLE.
LIBSA_NO_FS_SYMLINK is irrelevant here, and LIBSA_FS_SINGLECOMPONENT would
be pointless.
