	Change History (most recent first):

	   <SM6>	11/10/93	fau		Update from SuperMunggio <SMG2>.
	  <SMG2>	 9/29/93	chp		Add common unsigned types: uchar, ushort, ulong, uint.
	   <SM5>	  8/5/93	JDR		sync with Reality, moved NumVersion from Files.h
		<15>	 8/28/92	DCL		Fixed enums with commas before the closing brace. MPW now
									complains.
		<14>	 6/11/92	DCL		Cleanup & formatting to match Interface Stacks. Happy Happy Joy
									Joy.
		<13>	  5/5/92	DCL		For New Inside Mac: Moved definition(s) of 'style' to Types to
									break a circular dependancy. It won't work in QDText (the
									NIIM-correct place for it)  Yuk.  Someday we've got to find a
									better place.
		<12>	 2/17/92	MH		Changed noErr back to #define.  Turned out that changing it to
									an enum  <11> was the wrong thing to do for some end users, even
									though it was not problem for the Blue Build.     ---AND---
									Moved def of extended80 here from SANE.h and expanded the
									defintion so that it is defined as extended when mc68881 is off.
									This type is now used in several different interface files where
									extended used to be used. The extended type varies with the
									setting of mc68881, but toolbox and os interactions must use an
									80 bit  rather than 96 bit type.
		<11>	11/11/91	MH		redefine noErr as an enum intead of #define. To match errors in
									errors.h, and provide better type checking.
		<10>	 7/31/91	JL		Updated Copyright.
		 <9>	 1/27/91	LN		Checked in Database generate file from DSG. Added
									SystemSevenOrLater and SystemSixOrLater flags and rearranged
									file.
		 <8>	  1/3/91	JDR		(dba) Adding Str32 type for AppleTalk.h
		 <6>	12/14/90	dba		<JDR> add Ptr types to match Pascal
		 <5>	 11/4/90	dba		get rid of useless const in front of the StringPtr in the Length
									inline for C++ (it is impossible to make an inline that takes
									const strings, but returns a non-const unsigned char reference
									for the length); added constStr63Parameter, constStr32Parameter,
									constStr31Parameter, constStr27Parameter, constStr15Parameter;
									changed DebugStr, SysBreakStr, and SysBreakFunc to take const
									parameter
		 <4>	  10/9/90	JAL		Changed length definition.
		 <3>	  7/2/90	PKE		Moved definition of LangCode here from Packages.h.
		 <2>	 5/29/90	ngk		Added definition of ScriptCode, was in Packages.
		 <1>	12/17/89	CCH		Adding for the first time into BBS.
	   <1.1>	 11/9/88	CCH		Fixed headers and removed projector resource.
	   <1.0>	 11/9/88	CCH		Adding to EASE.
