Bug#364408: synfigstudio: FTBFS (amd64): cast from 'studio::DockDialog*' to 'int' loses precision

[Andreas Jochens]

Package: synfigstudio
Version: 0.61.05-1
Severity: important
Tags: patch

When building 'synfigstudio' on amd64/unstable,
I get the following error:

dockbook.cpp:218: warning: comparison is always false due to limited range of data type

With the attached patch 'synfigstudio' can be compiled on amd64.
