-// Define BitScanReverse64 and BitScanReverse
-// Per MSDN, BitScanReverse64 or BitScanReverse will search the mask data from most significant bit (MSB) 
-// to least significant bit (LSB) for a set bit (1).
-// If one is found, its bit position is returned in the out PDWORD argument and 1 is returned.
-// Otherwise, 0 is returned.
-//
-// On GCC, the equivalent function is __builtin_clzll or __builtin_clz. It returns 1+index of the most
-// significant set bit, or undefined result if mask is zero.
