Subject: Fix build failure on hosts with gcc 10
X-Git-Url: http://git.ipfire.org/gitweb/?a=commitdiff_plain;h=cb0ec03060fc0504c22e6df6003381aa3e8c0964;p=thirdparty%2Fshadow.git

Fix build failure on hosts with gcc 10

We cannot just uname these unused parameters because gcc 10
need them. There will be error like below with gcc 10:

  lib/copydir.c:103:11: error: parameter name omitted

The Debian bullseye uses gcc 10 by default.

Most of the changes are done manually. Some changes in tests/unit
are done via the following shell command:
sed -i -e 's#void \*\*#MAYBE_UNUSED void \*\* _1#g'  tests/unit/test_*.c

Closes: <https://github.com/shadow-maint/shadow/issues/1530>
