The only way to find out whether cmath is safe to use in include/osg/Math is to do it and then get the community to test across the full set of platforms. Problem areas are likely to be HP-UX, AIX, Solaris and IRIX. The later being the most likely to be a problem but it's also not something we official support now as no one tests on that platform that I'm aware of. Perhaps we could put a CMAKE variable into control whether to use cmath or math.h in case using cmath is problematic. This does add complexity though and if we don't need it it'll be a waste of time. There is no way for me to know until we do wider testing.
