Build Problems due to deprecations (linux)

[Robert Lichtenberger]

 I've tried to run a build of OpenJFX and it fails due to some deprecations
within gtk-2:

Questions:

* Should I open a bug for that?

* How can I turn off  -Werror to proceed with the local build for now. I
thought there was something in
https://wiki.openjdk.java.net/display/OpenJFX/Building+OpenJFX but I can't
find it (anymore)


Best regards,
