Something like.   The app that catches a dll-thrown exception will of course
also need to link against cyggcc-3.dll

If a dll catches its own exceptions, can use a static libgcc.a.

libgcc.a contains the generic EH code.  My tests with gcc-3 indicates that I
probably also need a part of libsupc++.a (a convenience lib when building
libstdc++.a. ) for C++   Likewise, for ObjC, need libobjc.dll.
