+*	Copyright (c) 1985-1991, Microsoft Corporation. All rights reserved.
+*
+*Purpose:
+*	defines vprintf() - print formatted data from an argument list pointer
+*
+*Revision History:
+*	09-02-83  RN	original printf
+*	06-17-85  TC	rewrote to use new varargs macros to be vprintf
+*	04-13-87  JCR	added const to declaration
+*	11-06-87  JCR	Multi-thread support
+*	12-11-87  JCR	Added "_LOAD_DS" to declaration
+*	05-31-88  PHG	Merged DLL and normal versions
+*	06-15-88  JCR	Near reference to _iob[] entries; improve REG variables
+*	08-18-89  GJF	Clean up, now specific to OS/2 2.0 (i.e., 386 flat
+*			model). Also fixed copyright and indents.
+*	02-16-90  GJF	Fixed copyright
+*	03-20-90  GJF	Made calling type _CALLTYPE1, added #include
+*			<cruntime.h> and removed #include <register.h>.
+*	07-25-90  SBM	Replaced <assertm.h> by <assert.h>, <varargs.h> by
+*			<stdarg.h>
+*	10-03-90  GJF	New-style function declarator.
