cysignal example does not compile in cygwin #114

The example uses # distutils: language = c++. However, after invoking python setup.py build in the example directory. I get the following output:

$ python setup.py build

I guess gcc cannot spawn g++ in cygwin.

That error doesn't seem related to cysignals at all. It looks like a problem with your Cygwin or Python installation. Is g++ installed?

This problem is fixed using the correct windows user to open the cygwin shell.
