I looked into this.  It seems that when CWSDPMI is present, the PMODE
stub is unable to transfer execution to the COFF image.  I'm not sure
whether the fault is in PMODE or in CWSDPMI (MWDPMI works fine, and I
assume Windows too), but further debugging would require rebuilding
PMODE, and I don't have any assembler that understands the syntax of
PMODE's source files.  I suppose it wouldn't be too difficult to
convert PMODE sources to djasm syntax, but I don't know how to do that
either.
