/*
 *  ======== std.h ========
 *  DSP-BIOS Bridge driver support functions for TI OMAP processors.
 *
 *! Revision History
 *! ================
 *! 16-Feb-2004 vp	GNU compiler 3.x defines inline keyword. Added appropriate 
			macros not to redefine inline keyword in this file.
 *! 24-Oct-2002	ashu	defined _TI_ and _FIXED_ symbols for 28x. 
 *! 24-Oct-2002	ashu	defined _TI_ for 24x.

 *! 26-Nov-1996 kw: 	merged bios-c00's and wsx-a27's <std.h> changes
 *!			*and* revision history 
 *! 12-Sep-1996 kw: 	added C54x #ifdef's
 *! 21-Aug-1996 mf: 	removed #define main smain for _21_
 *! 14-May-1996 gp:     def'd out INT, FLOAT, and COMPLEX defines for WSX.
 *! 11-Apr-1996 kw:     define _W32_ based on _WIN32 (defined by MS compiler)
 *! 07-Mar-1996 mg:     added Win32 support
 *! 06-Sep-1995 dh:	added _77_ dynamic stack support via fxns77.h
 *! 27-Jun-1995 dh:	added _77_ support
 *! 16-Mar-1995 mf: 	for _21_: #define main smain
 *! 01-Mar-1995 mf: 	set _20_ and _60_ (as well as _21_ for both)
 *! 22-Feb-1995 mf: 	Float is float for _SUN_ and _80_
 *! 22-Dec-1994 mf: 	Added _80_ definition, for PP or MP.
 *! 09-Dec-1994 mf: 	Added _53_ definition.
 *! 22-Nov-1994 mf: 	Ptr is void * everywhere.
 *!			Added definitions of _30_, etc.
 *! 23-Aug-1994 dh	removed _21_ special case (kw)
 *! 17-Aug-1994 dh	added _51_ support
 *! 03-Aug-1994 kw	updated _80_ support
 *! 30-Jun-1994 kw	added _80_ support
 *! 05-Apr-1994 kw:	Added _SUN_ to _FLOAT_ definition
 *! 01-Mar-1994 kw: 	Made Bool an int (was MdUns) for _56_ (more efficient).
 *!			Added _53_ support.
