This was implied:  If `__osmode' is zero and `__emx_env' and $0180 is zero
as well, then it is DOS without DPMI.

Once again the three EMX modes as a tabular:

    __osmode        __emx_env and $0180          system

     nonzero           doesn't matter             OS/2
        0                 nonzero            DOS with DPMI
        0                    0              DOS without DPMI
