Ah, you caught me. The 4 XPASSES were the result of mild version skew
between the times I did the 'cvs update' on the two source trees; they
were unrelated to the code changes.
In fact, when I ran the test suite correctly I discovered a number of
failed tests due to output changes (since now GDB is less aggressive
about guessing the type about symbols without debugging information).
After applying the following patch, I now get identical output from
the test suite before- and after-patch.
