////
//// -DNDEBUG | Disable debugging mode. Use always.
////
//// -DIS_64BIT | Compile in 64-bit mode. Use on 64-bit systems.
////
//// -DBIGENDIAN | Should not be used on Windows
////
//// -DNO_PREFETCH | Disable use of prefetch asm-instruction. A must if you want the
//// | executable to run on some very old machines.
////
//// -DUSE_BSFQ | Use bsfq asm-instruction. Works only in 64-bit mode.
//// | Works with ICC and GCC, not with MSVC. Gives a small speed up.
////
//// -DUSE_POPCNT | Add runtime support for use of popcnt asm-instruction.
//// | Works only in 64-bit mode. For compiling requires hardware
//// | with popcnt support. Around 4% speed-up.
