This comment implies that the problem was probably fixed in gdb-6.7
which is now over two years (and three releases ago).  Is the comment
wrong, or do we now support this.  Given the status of the VFP support
in GDB, I would really expect that someone wanting to debug VFP would
need a more recent version of the debugger than 6.6 anyway, so I
wouldn't see that as a reason for keeping the old numbering.
