I would expect that would be the case.  

Do we need to have a check to detect a buggy compiler that takes the
syntax but produces an incorrectly initialized array?  I could add a
test to ensure that HEADER comes out BOLD, etc. (or we may already
have such a test) and then reorder these lines in this patch, if
that is the kind of breakage we anticipate.
