Well under solaris I don't think there is a sqrtf so we'd have to do
some nasty stuff that would result in uglier code.

maybe a typedef in some header for SQRTF SQRTL etc....

If you do a search through the board about the comments you'll see the
changes I had to do on solaris and a note that was gcc specific.
If you were using solaris's native compiler which I am slowly trying
to get working btw... You'd have to do something different.
I'm not sure what that is exactly at this stage, my gut tells me
sqrt is just overloaded with solaris's compiler and it figures it out
