$NetBSD: patch-libkms_vmwgfx.c,v 1.3 2015/05/07 06:31:06 wiz Exp $

Provide compatibility errno number for non-Linux.
|
|
|
|
From FreeBSD ports for graphics/libdrm version 2.4.84
|
|
|
|
# the defintion of ERESTART is behind a check for _KERNEL, but
|
|
# defining that causes errno to not be defined. fortunately, there's
|
|
# an alternative switch. unfortunately, those differ by platform and
|
|
# _WANT_KERNEL_ERRNO is too recent to be part of any release, so just
|
|
# define ERESTART if we still don't have it after including errno.h
