New method for preventing compile-time calculation of degree constants. Commit 65abaab547a5758b tried to prevent the scaling constants used in the degree-based trig functions from being precomputed at compile time, because some compilers do that with functions that don't yield results identical-to-the-last-bit to what you get at runtime. A report from Peter Eisentraut suggests that some recent compilers are smart enough to see through that trick, though. Instead, let's put the inputs to these calculations into non-const global variables, which should be a more reliable way of convincing the compiler that it can't assume that they are compile-time constants. (If we really get desperate, we could mark these variables "volatile", but I do not believe we should have to.)
