Derive copyright year from the git commit date This solves problems like the need to update test suite on every New Year's Eve. * Makefile.am (dist-hook): Generate .year. * copyright-year-gen: New file. * configure.ac (copyright_year): New m4 variable, defined as the output of copyright-year-gen script. (AC_COPYRIGHT): Use it. (COPYRIGHT_YEAR): New output variable and preprocessor macro. * strace.c (print_version): Use COPYRIGHT_YEAR. * strace.spec.in (%prep): Save the value of COPYRIGHT_YEAR autoconf variable to .year file. * tests/strace-V.test (config_year): New variable, derived from config.h. Add sanity checks for $config_year and use it in expected output. Reported-by: Andreas Schwab <schwab@suse.de> 2017-04-04 14:30:39 +02:00			`#! /bin/sh`

copyright-year-gen: workaround for old git versions Apply the same treatment to this script as the one in v4.18-278-g295cf32. * copyright-year-gen <year>: Change format to format:%cD, remove --date, supply output as a -d option argument to date +%Y. 2017-08-27 18:29:05 +02:00			`year="$(date +%Y -d "$(git show --format=format:%cD --no-patch)")"`
