#7 Use gzip --no-name in manual compression for reproducible builds
I'm looking into build reproducibility issues in NixOS [0] and noticed that the manual is gzipped without the --no-name argument [1]. I was wondering if you would be interested in fixing this upstream. I've attached a patch for convenience.

Thanks for your patch! I wasn't even aware that gzip by default put a timestamp in compressed data, it seems as if bzip2 and xz does not. Your patch has been applied to the svn repo, however I do not know which year next official release will be.
Indeed, bzip2 and xz never did that. And gzip-1.9 even stopped embedding timestamps for pipes, because that made tar cz output unreproducible.
