[XML-SIG] PYXML-0.6.5 build problem on Cygwin 133

[Arno Waschk]

Dear people,

while trying to build your nice Python XML v0.6.5 I get the following 
error which I cannot solve:

[...]

I am on a fresh Cygwin 1.3.3 installation, following your README 
instructions ("python setup.py build" etc.)

Am I doing something wrong?
Do you need more information?

Thank you in advance
