If I recall, the way we got "blow" to build was as follows...

in main.c- controlsWRTobject()

..
        if (PadStatus & PADRup)
                {
#ifdef __MWERKS__
                viewFrom.vx = (viewFrom.vx*102)/100;
                viewFrom.vy = (viewFrom.vy*102)/100;
                viewFrom.vz = (viewFrom.vz*102)/100;
#else
                viewFrom.vx *= 1.02;
                viewFrom.vy *= 1.02;
                viewFrom.vz *= 1.02;
#endif
                }

        if (PadStatus & PADRdown)
                {
#ifdef __MWERKS__
                viewFrom.vx = (viewFrom.vx*100)/102;
                viewFrom.vy = (viewFrom.vy*100)/102;
                viewFrom.vz = (viewFrom.vz*100)/102;
#else
                viewFrom.vx /= 1.02;
                viewFrom.vy /= 1.02;
                viewFrom.vz /= 1.02;
#endif
                }
..

main.c-controlsWRTWorld

        if (PadStatus & PADRup)
                {
#ifdef __MWERKS__
                viewFrom.vx = (viewFrom.vx*102)/100;
                viewFrom.vy = (viewFrom.vy*102)/100;
                viewFrom.vz = (viewFrom.vz*102)/100;
#else
                viewFrom.vx *= 1.02;
                viewFrom.vy *= 1.02;
                viewFrom.vz *= 1.02;
#endif
                }

        if (PadStatus & PADRdown)
                {
#ifdef __MWERKS__
                viewFrom.vx = (viewFrom.vx*100)/102;
                viewFrom.vy = (viewFrom.vy*100)/102;
                viewFrom.vz = (viewFrom.vz*100)/102;
#else
                viewFrom.vx /= 1.02;
                viewFrom.vy /= 1.02;
                viewFrom.vz /= 1.02;
#endif


This converts  the floating point operations into integer oprerations.
