I had been using dosemu for a while and everything was fine, then after 
not using it for about 3mos I used it again and it is crashing when 
executing a Borland C++ makefile.

02:48 PM greg@bartleby >dosemu --v
dosemu2-2.0pre9
Revision: 7076
02:48 PM greg@bartleby >


The dosemu message is:

02:40 PM greg@bartleby >dosemu
ERROR: DPMI: unsupported SLDT dest 4e
ERROR: DPMI: unsupported SLDT dest 4e

The Makefile contents are:

MAKE Version 3.6  Copyright (c) 1992 Borland International

Available memory 114274304 bytes

         mkdir bin
         bcc ../Examples/Hello.c
         copy Hello.exe bin\Hello.exe
         del Hello.exe


The failure occurs when the "copy" is executed, or any command after bcc 
within the makefile.  If it is commented out the command "make 
hello.exe" works fine, if there is any command after bcc doesemu 
crashes.  I have even tried a simple "pause" after bcc and even that 
crashes.  This used to work fine.


Debug log is attached.
