bad news re: mingw exceptions

[Adam Megacz <gcj at lists dot megacz dot com>]

Ugh, this is really bad; C++ exceptions work, Java exceptions don't
(see below).

Can anybody tell me the differences in how they are implemented? CNI
would lead me to believe that they both get compiled the same way.

This stuff worked in the 12-Dec tree; has anything changed in
exception handling since then? I tried this same program in my old
12-Dec tree and it works.
