Looks pretty close to me ;-)

Without looking at the source, I can't suggest anything at all. There may
be issues related to the math library used in Cygwin (newlib), but again

it's going wrong?

The only change is in some libf2c library routines to get around windows
braindeadness (only etime and dtime if I remember correctly).
