So, at the very least, I should review the code in gdb/mi and see that
it compiles and doesn't do anything that shouldn't be done on
DOS/Windows.

That's actually not so good: the current build already overflows the
COFF limit of 64K lines in the debug info, albeit by a small margin;
adding more code will make things much worse...

Which reminds me: is there any reasonable way to prevent GDB from
linking in all those *read.c modules DJGPP users will never need?
I've never understood why do we have to pull into GDB things like
mipsread, os9kread, mdebugread, and others, which will never be used.
(Note that this setup predates multi-arch, so there's got to be some
reason which doesn't involve multi-arch.)  If I don't link those in, I
might save a significant part of memory footprint, and prevent the
line number overflow while at that.

Well, this already works for me (I'm using a month-old snapshot).
