Subject: If compiler allows it and if -DDIAG_COLOR_ALWAYS=yes is provided to
X-Git-Tag: v11.0.0~275^2~2
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=3b05f492d6940fd1de57200b5bb0ca80a2b6bec5;p=ceph.git

If compiler allows it and if -DDIAG_COLOR_ALWAYS=yes is provided to
cmake, turn on diagnostic colors always, even when compiler output
does not go directly to terminal (e.g., when piped to "less -R").
