*internal.h - contains declarations of internal routines and variables

*	Copyright (c) 1985-1990, Microsoft Corporation.  All rights reserved.
*
*Purpose:
*	Declares routines and variables used internally by the C run-time.
*	These variables are declared "near" for efficiency.
*	[Internal]
*
*Revision History:
*	05-18-87  SKS	Module created
*	07-15-87  JCR	Added _old_pfxlen and _tempoff
*	08-05-87  JCR	Added _getbuf (corrected by SKS)
*	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
*	02-10-88  JCR	Cleaned up white space
*	06-22-88  SKS	_canonic/_getcdrv are now used by all models
*	06-29-88  JCR	Removed static buffers _bufout and _buferr
*	09-20-88  GJF	Added declarations for _freebuf, _stbuf and _ftbuf.
*	01-31-89  JCR	Removed _canonic, _getcdrv, _getcdwd (see direct.h)
*	08-11-89  GJF	Changed DLL to _DLL
*	08-22-89  GJF	Fixed copyright (again)
*	08-29-89  GJF	Added prototype for _getpath()
*	10-17-89  GJF	Added _WINSTATIC macro
*	06-23-93  HTV	Kill the near keyword for FLAT
