* 02-01-88 JCR Added _dll_mlock/_dll_munlock macros
* 05-02-88 JCR Added _BHEAP_LOCK
* 06-17-88 JCR Corrected prototypes for special mthread debug routines
* 08-15-88 JCR _check_lock now returns int, not void
* 08-22-88 GJF Modified to also work for the 386 (small model only)
* 06-05-89 JCR 386 mthread support
* 06-09-89 JCR 386: Added values to _tiddata struc (for _beginthread)
* 07-13-89 JCR 386: Added _LOCKTAB_LOCK

* 04-06-90 GJF Added _INC_OS2DLL stuff and #include <cruntime.h>. Made
* all function _CALLTYPE2 (for now).

* 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
* and _getptd1_lk for Win32 under DEBUG.
* 10-03-91 JCR Added _cvtbuf to _tiddata structure
* 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.
* 08-21-92 GJF Merged 08-05-92 and 08-14-92 versions.
