[Paraview] build ParaView git on Windows7 64bit + MSVC2010 with vtkPythonCore errors

Wed Feb 16 10:42:29 EST 2011

Hi Xunlei, we just checked in a change into paraview/vtk that should fix
this. As you noticed python forces a header link to python27_d.lib when
building debug. To get around this (because most python packages for windows
don't come with debug python libraries), we undefine _DEBUG, include
python.h and then restore _DEBUG.

The problem with this is that any system level headers included from
python.h were also effectively included in 'release' mode when we undefined
_DEBUG. To work around this we determined the set of headers that python
includes and include them before undefining _DEBUG. This seems to address
the linking issues. Please give it a try and let us know if you experience
any other issues.

Thanks!
