Bug#776760: dot-forward: please make the build reproducible

[Chris Lamb]

Source: dot-forward
Version: 1:0.71-2
Severity: wishlist
Tags: patch
User: reproducible-bui...@lists.alioth.debian.org

Hi,

While working on the "reproducible builds" effort [1], we have noticed
that dot-forward could not be built reproducibly.

The attached patch removes timestamps from the build system. Once
applied, dot-forward can be built reproducibly in our current
experimental
framework.
