Thanks for the pointer.  Unfortunately, it does not answer my question
above.  Perhaps the earlier thread (to which it refers without stating
a URL) does, in which case I'd like to read that earlier thread.

Yes, but why?  It looks like getting rid of current_gdbarch is needed
to support the situation where multiple architectures are supported in
the same session (or maybe even in the same executable?).  That is why
I asked the second question above: the DJGPP native build of GDB
supports only a single architecture, and will ever support only that
single architecture.  So the question is: is there any particular
reason to get rid of current_gdbarch in go32-nat.c?
