/*****************************************************************************

 * COMPILER.H - Fine tune options and standardize macros between compilers.

 *

 *	This is a good place to put #pragma statements and other information

 *	specific to a given compiler.  Every module in PJ and all its subsystems

 *	and libraries will include this header file.

 *

 *	In addition to options, performance tuning statements, and so on, this

 *	header defines several macros which standardize operations between

 *	different compilers.  (IE, quirk-fixes.)  For example, a va_list type

 *	is an array-of-one under Watcom, but a scalar item under High C.  When

 *	you add a new compiler type, each of these macros must be defined as

 *	appropriate to your compiler.  Currently, these macros are:

 *

 *		NOFUNC			- A NULL pointer that works for function pointers.

 *		copy_va_list	- Copy a value from one va_list variable to another.

 *

 *	To add a new compiler, just clone one of the existing sections, change

 *	the compiler ID in the #if defined() statement, and add your options and

 *	quirk-fix macros.
