I don't know what the error message is about '-mno-cygwin'.
From another project where I was forced to use Windoze I dimly remember that this issue arises when compiling any C extension with the installed Python. That "-mno-cygwin" flag is defined deep inside setuptools itself and clashes with newer versions of the compilation tools which don't know that flag anymore. I may have some of the details wrong, but this is *not* an issue with the persistent package requiring a special build setup. The issue is at the Python level and how setuptools interacts with the compiler when building C extensions. In that project I was successfully building extensions using Cygwin. jens
