//// Configuration
////

//// For Linux and OSX configuration is done automatically using Makefile.
//// To get started type "make help".
////
//// For windows part of the configuration is detected automatically, but
//// some switches need to be set manually:
////
//// -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.
