The Windows/Cygwin compilation required commenting out the line

    #include "execinfo.h"

in "misc.c" as well as most of the body of the "misc_DumpCore" function.

The latest official SPASS sources can be downloaded from
http://www.spass-prover.org/. Be aware, however, that the official SPASS
releases are not compatible with Isabelle.

Viel SPASS!
