Hi all,

I am getting the following error when running `python setup.py install` for Numpy in Cygwin. This error happens on the latest as well as the maintenance branched for 1.5 and 1.6.

This should fix it: http://projects.scipy.org/numpy/ticket/1944.

Can you confirm that that works? Then I'll make the change in master.

Ralf
