// This file will select an implementation for a ThreadOps based on
// what ThreadOps.h selects. This method is for selecting the 
// source files, to improve portability. Currently, the project is
// based on the autoconf tool-set, which doesn't support conditional
// compilation well. Additionally, this should make the library 
// easier to port since its working around conditional compilation
// by using C++ features and people won't have to fiddle around with
// their make tool as much to compile the source
