Confirmed on x86_64-apple-darwin10.6.0. After reverting revision 168569
bootstrapping succeeds.

I am just about to test a patch for this. Java misses to build some type-nodes,
which are necessary for building the va_list type. It seems so that
unsigned_type_node is the culprit here.

Yeah, see also http://gcc.gnu.org/ml/gcc-patches/2010-12/msg00921.html (ignore
the linked PR though, it was a red herring.)

Issue here is that s390 uses for its va_list_node_type a record containing
long_integer_type_node type, which doesn't get initialized by java's decl.c

I think the http://gcc.gnu.org/ml/gcc-cvs/2011-01/msg00186.html check in and
all its follow-ups should be reverted, Java simply doesn't have a va_list type,
so it shouldn't be built.
Instead ix86_local_alignment should add va_list_type_node && to its checks
before using TYPE_MAIN_VARIANT on it.

I will prepare today a patch, which removes the part in java's decl.c, and adds
to i386 the additional check for initialized va_list_type_node in alignment
check.

Nevertheless, I see this more as a working hack, then as a solution. By looking
through the ChangeLog's of java FE, I see that in 1999 va_list_type_node was
added, but there is no line to be found in ChangeLog that this type
initialization was removed. So, it is in my understanding an regression.

That java's FE should use base type-machinery from tree.c would be something
good, but this design change should be done (or at least triggered) by one of
the java FE maintainers and looks to me in stage 4 a bit risky.
