I guess I misunderstood Jim's comments.

But are you sure?  :-)  If it's legal C++ then it, along with some other 
wierd-o edge cases should probably be added to a gdb.cp/struct0 test 
(someone with less rusty C++ than me can probably come up with a list).

Trying to include it in structs.exp would just be too messy.
