Boost.Python has always worked with Cygwin GCC, but if you don't use
-mno-cygwin, you have to use the cygwin version of Python (the one
installed when you select it in the Cygwin installer). Currently the
Python support in BBv2 on Windows and Cygwin is a total mess, which
may explain why it isn't working for you. I'm trying to fix that up
