Subject: [PATCH] lib/tests: 44-switch-body-fallthrough-not-default.c: Add
 test.

This test detects if the fallthrough in a switch statement falls to the
next case (good) or to the default case (bad).

* lib/tests/scaffold/44-switch-body-fallthrough-not-default.c: New file.
* build-aux/check-mescc.sh (mes_tests): Add it.
