From 73fbf8bd303053a091fc63d0ad741a071bb50fae Mon Sep 17 00:00:00 2001

Subject: Simplify test-snippets in configure.cmake

The main(void) signature obviates the need for unused parameters and
has existed since (at least) C89; so use that instead of the
old-fashioned argc/argv arguments we don't use in any of these tests.
