+//// -DNDEBUG       | Disable debugging mode. Use always.
+////
+//// -DNO_PREFETCH  | Disable use of prefetch asm-instruction. A must if you want the
+////                | executable to run on some very old machines.
+////
+//// -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.
