This is not a wxPython problem (I'll look into that, though).

What version of swig is reported by "swig -version"?
What version of gcc is reported with "gcc --version"?
What is reported for CFLAGS by "fgrep CFLAGS config.log"?

The combination of swig 1.3.31, gcc 3.4.4, and CFLAGS='-g -O2 -Wall ' works 
for me, but you need to install swig yourself to get 1.3.31 on Cygwin.
