Single precision is slower then double when using Cygwin\'s gcc-4/gfortran-4. gcc-3/g77-3 is OK.

CPU: Athlon XP 2500+ Barton

    Hi,

    I am very sorry for the looong delay, but I think I have gotten Windows fully supported in ATLAS 3.9.79. Using it, you can build 32-bit libs using either the cygwin compilers or the MinGW compilers, though you still need cygwin installed. The ATLAS installation guide that comes with the tarfile has Windows-specific installation instructions.

    Can you try 3.9.79 and let me know if it works for you?

    Many thanks,
    Clint

    Can you confirm this is still a problem with 3.9.79?

    Thanks,
    Clint
