Bug#775972: src:libgnomeui: FTFBS on x32: -Werror printf warnings

[Adam Borowski]

Package: src:libgnomeui
Version: 2.24.5-3
Severity: normal
Tags: patch
Justification: fails to build from source (but built successfully in the past)

Hi!
I'm afraid that libgnomeui has regressed due to use of -Werror.  It fails
to build on any architecture where time_t has a different size than long. 
That's not the case on any of current Debian release arch, but, per Linus'
decree, applies to any new 32-bit arch (because Y2k38).

Sadly, this regression hasn't been noticed for a year, as -ports archs are
allowed to go out of sync from release ones, and any reverse-dependencies
built happily using 2.24.5-2 which used different build flags.

A readable patch attached.  This one will fail in 23 years, but this code
needs to be rewritten for any arch other than x32 anyway.  A proper patch
would use hairy casts as there's no standard printf format string for
time_t.
