*			all function _CALLTYPE2 (for now).
*	04-10-90  GJF	Added prototypes for _[un]lockexit().
*	08-16-90  SBM	Made _terrno and _tdoserrno int, not unsigned
*	09-14-90  GJF	Added _pxcptacttab, _pxcptinfoptr and _fpecode fields
*			to _tiddata struct.
*	10-09-90  GJF	Thread ids are of type unsigned long.
*	12-06-90  SRW	Added _OSFHND_LOCK
*	06-04-91  GJF	Win32 version of multi-thread types and prototypes.
*	08-15-91  GJF	Made _tdoserrno an unsigned long for Win32.
*	08-20-91  JCR	C++ and ANSI naming
*	09-29-91  GJF	Conditionally added prototypes for _getptd_lk

*	02-17-92  GJF	For Win32, replaced _NFILE_ with _NHANDLE_ and
*			_NSTREAM_.
*	03-06-92  GJF	For Win32, made _[un]mlock_[fh|stream]() macros
*			directly call _[un]lock().
*	03-17-92  GJF	Dropped _namebuf field from _tiddata structure for
*			Win32.
*	08-05-92  GJF	Function calling type and variable type macros.
*	12-03-91  ETC	Added _wtoken to _tiddata, added intl LOCK's;
*			added definition of wchar_t (needed for _wtoken).
*	08-14-92  KRS	Port ETC's _wtoken change from other tree.
