Eliminate the -rdynamic option.  I don't see that this has ever been supported
by Cygwin gcc but I haven't specifically tested an older version.

If -rdynamic actually was accepted (I doubt that it did anything) in
older versions of gcc it was not removed by any patch that I applied to
gcc so undoubtedly this was done by the gcc 2.95.3 developers.
