[BUG] Wrong Python2.7 configuration

[BUG] Wrong Python2.7 configuration

[Pavel Fedin]

 Hello!

 During building Insight for Cygwin i hit this error:
--- cut ---

Py_FORMAT_PARSETUPLE(PyArg_ParseTuple, 2, 3);

 The problem obviously happens because of incorrect
HAVE_ATTRIBUTE_FORMAT_PARSETUPLE setting in python27/pyconfig.h. Likely
python's configure test is broken. The relevant discussion is here:

This only occurs in 64 bit Cygwin, afaics.  I reported this problem two
weeks ago on cygwin-apps(*) already.

Jason?  Yaakov?  Ping?

As a local workaround, I disabled the definition of
HAVE_ATTRIBUTE_FORMAT_PARSETUPLE in /usr/include/python2.7/pyconfig.h.

This problem is resolved by next patch:

The same patch for python2.x

 Me too. Just decided to report this in order to be fixed in subsequent releases.
