Plus, we get npycore which should help with Cygwin / FreeBSD / other systems without C99 stuff.

NumPy 1.4. is retracted and unsupported; likely better wait until 2.0 is released in some weeks.

(However, strictly speaking, the only problem with NumPy 1.4 was that of binary compatability with older versions; something Sage doesn't care about.)
