#369: Windows binary 0.5.2 for Python 2.5 requires SSE2

I have installed SciPy 0.5.2 for Python 2.5 on several Windows computers,
using the precompiled binary scipy-0.5.2.win32-py2.5.exe. This works fine
on some, but on others it crashes Python with an Illegal Instruction
exception. The crash is easy to find by running the test() suite or by
attempting to make any use of scipy.integrate.quad.
Digging into it, I see that the exception comes from _quadpack.pyd, and it
dies at a MOVSD instruction. MOVSD is an SSE2 instruction that is only
implemented on the more recent CPUs from both Intel and AMD.
