Alas, much of the relevant info is nowhere in the DJGPP docs, since it
has to do with general features of x86 protected-mode operation.

So the plan is to teach `symify' to print some of that diagnostics
automatically.  To this end, DJGPP v2.02 already has an improved
traceback which includes additional crucial information.

I don't know if I'll be able to improve `symify' in time for the v2.02
release (volunteers are welcome, as usual ;-).  In the meantime, if
anybody has descriptions of specific classes of bugs and how they are
reflected in the traceback, please post them here.

Posting a lot of case studies is also a good idea (see my message Re:
fsdb crashes post emacs).
