I know this. I have access to the Watcom C++ Compiler V?.0 which is able
to handle even 32-bit protected mode at DOS. *BUT* I'm going to write
a very simple operating system (in C++), and there I don't need
extenders but I want to load EXEs generated by TLINK. That's all, and I
think that could not be so difficult; but, considering I got no answer
to this question...
