I think this is red-herring. Does it really make sense to force
configuring long double as double if the C runtime and compiler do
support long double as a different type than double ? The problem is
only a concern on windows because of compilers bugs (or more exactly
compiler/runtime mismatch): on windows, long double are double, and so
long double functions are given 8 bytes double, which is why it should
work.

My only worry is related to ticket 891
(http://projects.scipy.org/scipy/numpy/ticket/891), which confused me
around this long double is double thing.

Anyway, that will be wait for 1.3.

cheers,

David
