//  01-Feb-1994 HV  Move messages to external file.
//  29-Oct-1993 HV  Change the version scheme.
//  15-Oct-1993 HV  Use tchar.h instead of mbstring.h directly, change STR*() to _ftcs*()
//  18-May-1993 HV  Change reference to messageTable[] to __MSGTAB.  The new
//                  (and more standard) mkmsg.exe output __MSGTAB instead
//                  of messageTable.  See message.h
//  10-May-1993 HV  Add include file mbstring.h
//                  Change the str* functions to STR*
//  08-Jun-1992 SS  add IDE feedback support
//  08-Jun-1992 SS  Port to DOSX32
//  23-Feb-1990 SB  Version No correctly displayed
//  31-Jan-1990 SB  Debug version changes
//  05-Jan-1990 SB  Rev no in std format; #ifdef LEADING_ZERO for old code
//  07-Dec-1989 SB  Changed CopyRight Years to 1988-90; Add #ifdef DEBUG_HEAP
//  06-Nov-1989 SB  Error messages now show NMAKE and not argv0
//  04-Sep-1989 SB  heapdump() has two extra parameters
//  18-Aug-1989 SB  For -z nothing done by makeMessage; Fix later
//  05-Jul-1989 SB  localize rest of the messages in makeError()
//  14-Jun-1989 SB  modified to localize all messages and auto update version no
//  05-Jun-1989 SB  modified heapdump(), has a previous member in the list too
//  14-Apr-1989 SB  modified heapdump() for better error messages when DEBUG
//  05-Apr-1989 SB  made functions NEAR; all funcs to one code segment
//                  modified heapdump() to give better heap violations
//  22-Mar-1989 SB  del call to unlinkTmpFiles() ;add call to delScriptFiles().
//  17-Mar-1989 SB  heapdump() has an additional check built-in
//  10-Mar-1989 SB  Changed makeMessage() for -z to get echo CMD's into PWB.SHL
//  16-Feb-1989 SB  changed makeError() and makeMessage() to handle -help
//  09-Jan-1989 SB  changes in makeError() to handle -help correctly
//  05-Dec-1988 SB  Added CDECL for makeError(), makeMessage(); Pascal calling
//                  #ifdef'd heapdump prototype
//  20-Oct-1988 SB  Changed some eoln comments to be in the same column
//  12-Oct-1988 SB  Made GetFarMsg() to be Model independent & efficient
//  17-Aug-1988 RB  Clean up.
//  24-Jun-1988 rj  Added doError flag to unlinkTmpFiles call.
