Subject: Make the build reproducible.
X-Git-Tag: v1.0.4~9
X-Git-Url: http://git.tue.mpg.de/?a=commitdiff_plain;h=2d0464872cec02b53f5bb5ca2a037cb764641c1f;p=lopsub.git

Make the build reproducible.

Whilst working on the Reproducible Builds effort [0] we noticed that
liblopsub could not be built reproducibly.

This is because it calls "gzip" manually without the -n
flag. This should have been reported by lintian via the
package-contains-timestamped-gzip tag.
