+////

+//// 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.

+////                | Locks and Condition Variables: these are not supported by Windows XP
