Hi! While working on the “reproducible builds” effort [1], we have noticed that pixmap 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. Please also consider this other bug from the reproducible builds team: https://bugs.debian.org/777430 Cheers, akira [1]: https://wiki.debian.org/ReproducibleBuilds
