This is a well-known problem and it cannot be fixed.  GCC's parser
throws out the typedef so the xml dump can't see it.  The same thing
happens when error messages get reported in pure GCC.  The gcc devs
cannot agree on whether messages with the typedef names or with the
real types are more useful.  Any attempt to bring up discussion on
this has failed to achieve anything but preservation of the status-quo.
