Bug#357897: FTBFS with G++ 4.1: dereferencing type-punned pointer will break...

[Martin Michlmayr]

Package: holotz-castle
Version: 1.3.8-1
Severity: important

Your package fails to build with G++ 4.1.  I'm filing this bug as
important for now, but when 4.1 will be the default compiler in
unstable (probably in a few weeks) I'll upgrade this to serious.
