word32 CheckRunTimeFastMath(void)
This function checks the runtime fastmath settings for the maximum size of an integer. It is important when a user is using a wolfCrypt library independently, as the FP_SIZE must match for each library in order for math to work correctly. This check is defined as CheckFastMathSettings(), which simply compares CheckRunTimeFastMath and FP_SIZE, returning 0 if there is a mismatch, or 1 if they match.
