[Numpy-discussion] Compiler change for Windows version between 22.214.171.124 and 1.0.4?
Wed Dec 19 19:35:35 CST 2007
Sounds like exactly the problem Jarrod Millman is working to solve.
The new binary uses SSE2 options which P3's and older Athlons don't
support. It sounds like Jarrod has found a machine he can use to
create the new binaries and solve the problem.
