I'm still getting a test failure with current master (commit 
99f609c6f3361e101cd665fbaad4a98f4631cab8) with 'make -j5 check' in an in-tree 
build. A failed mml-sec-tests.log attached.

(cd test && make -j5 lisp/gnus/mml-sec-tests) works. So perhaps it's a 
combination of a missing dependency and 'make -j'.
