It is not totally clear to me what you mean by 'standard MS-DOS makefiles'
since the 'make' program is a UNIX program, supplied by some MS-DOS
compilers as well (e.g. Borland).

I use such a version of make (Borland) together with DJGPP.
The only 'non-portability' I have encountered is the fact that the
MS-DOS make program (or better: MS-DOS itself) doesn't like commandlines
of more than 128 chars.

GCC as well as all programs using GO32 ('DJGPP') can be supplied 
with a 'link' response file to cope with this.
See example.

------------------------------ makefile ------------------------------------
#
PROG  = progname
OBJ   = obj1.o obj2.o
LIB   = -lm -lcurses
PCLIB = -lgr -lpc

.c.o:
        GCC -O -c $<

$(PROG): $(OBJ) $(PROG).o
        make $(PROG).lnk
        GCC -O -o $(PROG) @$(PROG).lnk $(LIB) $(PCLIB)

$(PROG).lnk: 
        for %o in (*.o) do echo %o >>$(PROG).lnk   # MS-DOS batch language
