Minor update to the patch: It now also sets TREE_USED for entry
masters in order to avoid bogus warnings for procedures with ENTRY
(cf. comment 6 in the PR, which like comment 0 is a 4.8 regression).
Still regtests cleanly. Ok?
OK with an extra test for comment 6.
Thanks a bunch. Committed as r193811. (A test for comment 6 was
already included in the updated test case I sent together with the
updated patch.)

Ah, yes, indeed. Didn't see it.
