[Bug mi/10586] Anonymous unions/structs not handled correctly under MI

Subject:  Anonymous unions/structs not handled correctly under MI

The patch below seems to fix this.  I may have missed something because the
thread suggests that any fix isn't that simple.  If that's so, the MI
testsuite overlooks it too because there are no unknown failures.
