Using npy_ prefix was a consciously designed feature :) I would prefer
avoid doing this, as it may cause trouble: sometimes, even if the foo
function is available, we may want to use npy_foo because it is better,
faster, more standard compliant.

For example, I remember that the few complex functions on Visual Studio
are broken, so even though they are detected, I have a MSVC ifdef to use
our own in that case.
