--- Comment #3 from yegorslists at googlemail.com --- Hallo Damian,

thanks for testing. Could you add your Tested-By tag to my patch e-mail? See
[1] for more information.

The warning are OK. re2c is an optional dependency and "Manually-specified variables" are common BR settings. If they cannot be applied, they are just ignored.
