Sorry for the delay in responding to this message.

Yes, it seems we could build Octave with our own "home-built" GCC that
has dwarf2 exception handling enabled, but as you say, then we would
probably also need to rebuild all the libraries (including
cygwin.dll?) that Octave uses.  Also, users would have to build .oct
files with this compiler.  It seems like a lot of trouble, and
confusing to the average user.  It would be much better if the GCC and
Cygwin people could agree on and implement a real fix.
