Well, most of the bitrot seems to have taken place after the 5.3
release.  So I'm not at all confident that it still works to your
satisfaction.  I'm working on the 32-bit SPARC target now, and I'm
pretty confident that I can get it in a shape where it works better
than GDB 5.3.  It's not until then that I'll replace the old code with
my new implementation.

Just out of curiosity.  What's the --target you use to configure the
GDB you're using to debug your embedded system?
