Well, I did some further testing, and as far as I can tell both the
standard DJGPP fpt emulator and the wemu one work as expected.

Notes:

   1. It seems that the standard setup doesn't really work, to use the
      ftp emulation add the old style (V1) lines:

      SET 387=N
      SET EMU387=C:/GNAT307/BIN/EMU387.DXE

      to your autoexec.bat and make sure the file emu387.dxe (normally
      in the directory \gnat307\bin) is in your path for both the
      development and target machines.

   2. An alternative is to link the the emulator library to your
      executable (the advantage being that the .dxe file doesn't
      have to be installed on the target machine), but unfortunately
      this library is not part of the standard EZ2LOAD distribution.
      Getting this library from the net is no solution since the current
      one is for DJGPP v2.01 (and contains some bug fixes, in collaboration
      with fixes to libm) and the current GNAT release is based on the
      -incompatible- DJGPP 2.00.

   3. Another option is getting the alternative wmenu library from the net
      (simtelnet/gnu/djgpp/v2misc) which includes both the .dxe and lib
      files. The advantage of wmemu is rumored to be that it is better
      debuggable. However, this port is rather old and might hold some
      supprises (although I didn't run in to any).

   4. Mike F. notes that he had some reports of conflicts between the
      tasking and the fpt emulation. More info is missing, and I again
      did not run into any problems here.

   5. Documentation notes that there has not been any significant testing
      of either emulator on real fpt-less machines, so beware.
