From 906ce869eb68a70b88a459f63dac8147ecc88a0c Mon Sep 17 00:00:00 2001 From: Jiri Slaby Date: Thu, 29 Sep 2016 09:55:18 +0200 Subject: configure: add option to enable timestamping It is pain for build systems to see __DATE__ or __TIME__ in sources as the build is not reproducible. So disable the timestamping by default and add an option to enable it if somebody is really after it.
