f730c8a9777b Remove some unused variables and options.inc which uFloat doesn't use, probably should never use, and was getting in the way of my testcase - but most importantly, remove the inline on hwSqrt which was causing very bad math on my compiler/machine. We may have to remove more inlining. A pity.
