The GPL-2.1 isn't a valid license. The copyright header says that "These tests adapted from glibc's string/test-strncat.c" and test-strncat.c is under the LGPL-2.1-or-later.
This was reported to us by Leah Rowe. Signed-off-by: Denis 'GNUtoo' Carikli <[email protected]> --- ChangeLog v1->v2: * Fixed the SPDX license identifier (LGPL-2.1+ like names are used Guix and I'm used to that, sorry for not spoting the issue).
