// TestGZIPFilesHaveZeroMTimes checks that every .gz file in the tree
// has a zero MTIME. This is a requirement for the Debian maintainers
// to be able to have deterministic packages.
//
// To patch a .gz file, use the following command:
//
//	$ dd if=/dev/zero bs=1 seek=4 count=4 conv=notrunc of=filename.gz
//
// See https://golang.org/issue/14937.
