Any chance you could provide patches to the standard
cygwin build scripts or gcc source if required or at
a minimum the write-up required to make it work.  I've
recently hit C++ problems w/ cygwin where the
exception handling didn't work like it does w/ Linux
(STL_port).  I'd like to be able to try the dwarf2 EH
to see if it fixes the problem.
