No, but if the data isn't important anyway, I figured we might as well load it with the default value as something useful for anyone that happens to read the line. Submitting what was in the systemd patch seemed embarrassing, but if you think it's more confusing then I'm happy to include some bogus text of your choosing. > I'm fine with this approach for compatibility with gcc < 4.9, but > the patch is corrupted by your mail client.

Subject: [PATCH] build: Do not force diagnostics-color flag
The -fdiagnostics-color flag is only available on GCC >= 4.9, for
older versions this could raise an error in certain circumstances
(such as when using ccache). Instead, since -fdiagnostic-color=auto
by default in gcc-4.9, simply set the required environment variable
to the default one if it's undefined.
Based mostly on the systemd commit f44541bc by Michal Schmidt.
