My apologies.  I saw the code and assumed we had gone ahead with the uniform
array alignment idea.  Rather, that was done back in August:

2000-08-16  Andrew Haley  <aph@cygnus.com>

        * typeck.c (build_java_array_type): Rewrite code to do array
        alignment.  Take into account back-end macros when aligning array
        data.  Remove setting of TYPE_USER_ALIGN; Java doesn't allow the
        user to set alignment. Fixes gcj/252 and 160.

I'm puzzled that it didn't break until recently.  It should never have worked at
all.

Sounds reasonable.
