[Reproducible-builds] Bug#788747: 0xffff: please make the build reproducible

[Dhole]

Source: 0xffff
Version: 0.6.1-2
Severity: wishlist
Tags: patch
User: reproducible-builds at lists.alioth.debian.org
Usertags: timestamps

Hi!

While working on the “reproducible builds” effort [1], we have noticed
that 0xffff could not be built reproducibly.

The attached patch removes extra timestamps from the build system.
Specifically, the patch avoids the the usage of the __DATE__ and
__TIME__ C macro which embed timestamps during the compilation and make
the package build unreproducibly.
Once applied, 0xffff can be built reproducibly in our current
experimental framework.
