/**      

 * @file

 *

 * Preprocessor symbols for canonical identification of OS, architecture,

 * and compiler.  Scrupulous use of these and only these symbols avoids

 * portability problems due to inconsistent platform tests.

 * 

 * For a given target platform XYZ, we define three symbols with the value 1:

 *

 * \li \c LT_OS_XYZ defines the operating system

 * \li \c LT_COMPILER_XYZ defines the compiler

 * \li \c LT_ARCH_XYZ defines the HW architecture

 *

 * Note for Windows, we treat WIN32, WIN64, and WinCE as distinct OS's, but

 * bothwill define LT_OS_WINDOWS for the typical cases.

 *

 * See the file lt_platform.h for full details.

 *

 * @note This file is C-callable.
