From: Andreas Färber Date: Thu, 31 Jan 2013 14:40:14 +0000 (+0100) Subject: block/raw-posix: Build fix for O_ASYNC X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=fdf263f63fad86b04032da86686a952edfe4644f;p=qemu.git block/raw-posix: Build fix for O_ASYNC Commit eeb6b45d48800e96f67ef2a5c80332557fd45ddb (block: raw-posix image file reopen) broke the build on OpenIndiana. illumos has no O_ASYNC. Exclude it from flags to be compared and instead assert that it is not set where defined. Cf. e61ab1da7e98357da47c54d8f893b9bd6ff2f7f9 for qemu-ga.
