Something along the following lines seems to do the trick, by which I mean 
it compiles in 2.012 though I believe the syntax should be compatible with 
D1:

enum FPPrecision : short
{
    Single = 4210,
    Double = 4722
}

void setFPCtrlWord(FPPrecision precision)
{
    asm
    {
        fldcw precision;
    }
}

Having said that it might be advisable to use 'fstcw' and bitwise operations 
to alter the specifics of the control-word that you require:
