But isnt this a bit runtime-slow Matt?
BTW I looked into your ct problems. VC 7.1 has some neat specialisations.
(Doesnt work on gcc)
have you tried masks?
Basically 7 dimensions --> 127 (I think) mask possibilities
If interested Will try to look out the code.
Results in a big header .... but gives fast compile.
