I believe this will require more than one approval.
You got mine.

P.S.: An interesting case:  there was a blank line too many in gdbtypes.c and you replaced it with a useful line of
code.  Normally we avoid formatting fixes to be mixed with the actual code changes, but I admit having to introduce a
new line of code exactly there is sort of an opportunity to get things right.  I will let Andrew have the final say on
that.
