// HOW TO COMPILE AND LINK THIS WITH THE LATEST VERSION OF DDS
//
// The following is suggested:
//
// - obtain the latest dds11x.cpp and dds11x.h file for version 1.1x
// of Bo Haglund's DDS and copy them into this directory
//
// Linux: compile and link as follows:
// g++ -O2 -Wall -o ./ddd ddd.cpp dds11x.cpp defs.cpp timer.cpp giblib.cpp rng.cpp
//
// Windows: compile and link as follows:
// g++ -O2 -Wall -o ddd.exe ddd.cpp dds11x.cpp defs.cpp timer.cpp giblib.cpp rng.cpp
//
// for debugging change the switch '-O2' to '-g'
//
// Note: on MingW you must have _WIN32 defined to compile code in timer.cpp
//
