*	[Internal]
*

*	11-05-87  JCR	Added _buferr
*	11-18-87  SKS	Add __tzset(), made _isindst() near, remove _dtoxmode
*	01-26-88  SKS	Make __tzset, _isindst, _dtoxtime near/far for QC

*	06-22-88  SKS	_canonic/_getcdrv are now used by all models
*	06-29-88  JCR	Removed static buffers _bufout and _buferr
*	08-18-88  GJF	Revised to also work for the 386 (small model only).
*	09-22-88  GJF	Added declarations for _freebuf, _stbuf and _ftbuf.
*	01-31-89  JCR	Removed _canonic, _getcdrv, _getcdwd (see direct.h)

*			stuff. Also, removed some (now) useless preprocessing
*			directives.
*	03-21-90  GJF	Put _CALLTYPE1 into prototypes.
*	03-26-90  GJF	Added prototypes for _output() and _input(). Filled
*			out the prototype for _openfile

*	12-04-90  SRW	Added _osfile back for win32.  Changed _osfinfo from
*                       an array of structures to an array of 32-bit handles
*			(_osfhnd)
*	04-06-91  GJF	Changed _heapinit to _heap_init.
*	08-19-91  JCR	Added _exitflag
*	08-20-91  JCR	C++ and ANSI naming

*	01-08-92  GJF	Added prototype for _GetMainArgs.
*	01-18-92  GJF	Added _aexit_rtn.
*	01-22-92  GJF	Fixed definitions of _acmdln and _aexit_rtn for the
*			of crtdll.dll, crtdll.lib.
*	01-29-92  GJF	Added support for linked-in options equivalent to
*			commode.obj and setargv.obj (i.e., special declarations
*			for _commode and _dowildcard).
*	02-14-92  GJF	Replace _nfile with _nhandle for Win32. Also, added
*			#define-s for _NHANDLE_.
*	03-17-92  GJF	Removed declaration of _tmpoff for Win32.
*	03-30-92  DJM	POSIX support.
*	04-27-92  GJF	Added prototypes for _ValidDrive (in stat.c).
*	05-28-92  GJF	Added prototype for _mtdeletelocks() for Win32.
*	06-02-92  SKS	Move prototype for _pgmptr to <DOS.H>
*	06-02-92  KRS	Added prototype for _woutput().
*	08-06-92  GJF	Function calling type and variable type macros.
*	08-17-92  KRS	Added prototype for _winput().
*	08-21-92  GJF	Merged last two changes above.
*	08-24-92  PBS	Added _dstoffset for posix TZ
*	10-24-92  SKS	Add a fourth parameter to _GetMainArgs: wildcard flag
*			_GetMainArgs => __GetMainArgs: 2 leading _'s = internal
*	10-24-92  SKS	Remove two unnecessary parameters from _cenvarg()
*	01-21-93  GJF	Removed support for C6-386's _cdecl.
*	03-30-93  GJF	__gmtotime_t supercedes _dtoxtime.
*	04-17-93  SKS	Add _mtterm
*	05-11-93  SKS	_mtinit now returns success (1) or failure (0)
*			_C_Termination_Done needed in all models (for DLLs)
*	06-02-93  CFW	Add _flswbuf, _filwbuf protos.
*       07-15-93  SRW   Added _capture_argv function prototype
*       09-22-93  CFW   Test for invalid MB chars using global preset flag.
