This is due to a gccxml bug: http://www.gccxml.org/Bug/view.php?id=7572 You might get away with it by re-scanning API definitions from within the cygwin environment (./waf --python-scan). However the most likely solution will probably have to be that we disable python bindings in CygWin. If you really care about Python bindings, try building with mingw and native python instead.
