If I run your examples here I get for xx{ }fprint
195.09 382.683 555.57 707.107 831.47 923.88
980.785 1000. 980.785 923.88 831.47 707.107
555.57 382.683 195.09 0.000000000000122465 -195.09 -382.683

-980.785 -923.88 -831.47 -707.107 -555.57 -382.683
-195.09 -0.000000000000244929 195.09
Which looks correct. When adding 'xx{ 32 1 }FWT' i get the same values
as listed at the bottom of walsh.fs.
This is with gforth-0.7.0 amd64 on debian squeeze. Same results on
32-bit mips.
Maybe there's something wrong with the windows version of gforth? Can
you add a '~~' tracer in wtest-init, so that it reads
xx{ I ~~ } F!
What does it output?
BTW gforth comes with its own version of fsl-utilg.fth, try
require fsl-util.4th
cheers,
David
