We build xpra with -Werror which triggers an error and stops the build
if there are any warnings at all, and the Debian version of the GTK
headers generate a warning.
There are other problems with the libav headers too.
You can find the patches that need to be applied to build on Debian
based systems here:
(which patches need to be applied varies from one version to another)
