Ok, I'm happy to start this now. Someone (Nick?) let me know what I need to do.

It would be nice to see Tristan's changes to BFD from November 14th
make it into 7.5.1. Without them you get a whole bunch of errors every

working after that, but it's ugly and gives the impression that GDB is

I don't know enough about GDB yet to know what user-visible problems
my patch fixes. Without it, abfd->start_address can be NULL when it
