[AstroPy] PyWCS build failure on Windows 7 and Windows XP with EPD

[Tom Aldcroft]

Hi -

I'm am unable to build PyWCS on a Windows 7 and Windows XP machines
using the latest EPD 7.0.2.  In both cases I get the same compiler
error.   Any hints or advice would be most welcome.  Below I include
configuration information and the build log.

Thanks, Tom
