Oh, I misunderstood this. Have you tried building other C extension
modules before? How about C++ extension modules? You might try and
create a minimal SWIG C++ example and see if you can build that, and if
not you could submit that as a bug to the SWIG/cygwin devs. What is
your gcc version? Can you upgrade gcc or are you using the latest?
I use the mingw environment under win32, but not cygwin. That way you
can use gcc and gnu tools, but native win32 python and binaries. Much
