Hi! While working on the “reproducible builds” effort [1], we have noticed that fortunes-bg could not be built reproducibly. The attached patch sets the mtimes of all files which are modified during the built to the date of the last changelog entry in order to produce files with reproducible metadata. Cheers, akira [1]: https://wiki.debian.org/ReproducibleBuilds
