      I have not had time lately to work on quaternions ond octonions, 
as I am working on special functions first, so the CVS version and the 
realease version should be identical (I'd have to check, as this is from 
memory). I plan on going back to them afterwards (my to-do list for them 
is still quite big).

      That's good. Should also work with MetroWerk's codeWarrior.

      I have little hope for that compiler. Last time I tried to 
shoehorn the library, the problems were just too numerous, due to to 
that compiler's non-compliance with the standard.

      I'd like to know. I do not currently have access to an installed 
copy of this compiler, but it's one for which quite some energy was 
expended to make things work.

      Please let me know as well, as this is obviously one of the more 
important targets (and I also do not have an installed copy handy, 
though I know i should...).
