/*
 * Package Operations:
 * ===================
 * Programmatically builds C++ source code.
 * - supply command line arguments for file name(s) and options, e.g.:
 *   ..//..//builder.cpp /EHa
 * - returns Exit code 0 if successful
 *
 * Required Files:
 * ===============
 * Builder.cpp
 *
 * Compiler Command:
 * =================
 * cl builder.cpp /EHa
 *
 * Maintenance History:
 * ====================
 * v2.1 : 06 Nov 08
 * - fixed bug that caused failure if LIB or INCLUDE were already defined
 * v2.0 : 21 Oct 08
 * - changed design to avoid need to copy compiler's components to local 
 *   application directory
 * v1.0 : 16 Aug 07
 * - first release

// supressing compiler warning 4005 - Macro Redefinition
// - Needed here because we need to prevent compiler from
//   redefining the identifier GetEnvironmentVariable to 
//   GetEnvironmentVariableW.
// - That's something triggered by the inclusion of Windows.h in
//   HiResTimer.h.  I haven't figured out a more graceful way of
//   handling this yet.
