How many "Fast Math" routines for XL/XE are there?

The Ahl Benchmark post got me thinking about this.  These are ones that I know about (they may share some common code):

Newell (the original AFAIK)
CSS UltraSpeed Plus OS
Turbo Basic XL
Basic XE
MyIDE OS
Charles Marslett (MyDos author)
OS++

I suspect there are a few others...  It might be interesting to run the Ahl Benchmark with a common Basic to see the difference in the the various math packs.
