Zortech C and C++ simply totally ignore #pragma lines. This is for
ANSI C compatibility. It also enables one to create source code that
can be compiled under other compilers that do support some pragmas, as in:

	#if BRAND_X_COMPILER
	#pragma brand x specific feature
	#elif BRAND_Y_COMPILER
	#pragma same feature only different syntax for brand y
	#endif

Whether the ANSI C idea of pragmas is going to be useful in practice
only time will tell. I'm sure C++ will follow the lead.
