But the thing is: sqrtf() is a C99 function. And I wonder if blender should=
 be=20
using either

	a) Code that complies to a recent (i.e. C99) standard=20

or

	b) Code that complies to an older albeit probably more portable standard
	(i.e. ANSI)

I for one would rather pick a), but if someone comes up with a good reason =
for=20
b)...

=20
=2D-=20
