Like this:

    #include <sys/movedata.h>
    #include <sys/segments.h>
    #include <stubinfo.h>

    char doscmd[128];
    movedata(_stubinfo->psp_selector, 128, _my_ds(), (int)doscmd, 128);

Now doscmd[0] has the length of the command tail, while doscmd[1] to
the end is the tail itself.  Warning: it's in DOS command tail format,
and thus is not terminated by a null character!

Also note that the command tail you get from a DJGPP program invoked
by another DJGPP program will not be what you expect: it will be
something like " !proxy 0xNNNN 0xKKKK".  See section 16.4 of the FAQ
for more about this.
