 * IMPORTANT:  The object libraries shipped with this distribution were built
 *             using the following compile options.  These options should not
 *             be removed and should be used when building code that links
 *             these object libraries.  Note as well that the NUMERIC_SECURE
 *	       compile option is used for numeric versions of these object
 *	       libraries.  This option is defined via the makefiles included
 *	       with this distribution.  To ensure that these options are 
 *	       defined when compiling user code, include this header file
 *	       or use the define option available for your specific compiler
 *
 *             Note as well that the libraries have been built using the SYN
 *             compile option to support systems with synthesized receivers.
 *             This compile option is not required and can be defined according
 *             to your specific system configuration.
 *
 *             Refer to the makefiles and documentation regarding builds of this
 *             software for more information on compile options.
