  I've done that.

  I use my own linker (you can download it from my web page)
to link a combination of .o files produced by DGJPP and
.obj files produced by TASM (NASM would work almost as well)
into an image that can be put directly into the FLASH memory
of the target system.

  When doing something like that you ought to replace a few
OS dependant low level routines in the C library, so that
common routines like printf can be used in your environmenmt.
I didn't do that.  I avoided using the entire C library.  My
C routines only call others of my own routines;  No printf or
other standard routines.
