How do I translate the following piece of DOS-code to linux?

static union {
  unsigned int *a; // One 32 bits address
  unsigned long l; // One 32 bits long
  unsigned int w[2]; // Two 16 bits words
  unsigned char b[4]; // Four 8 bits bytes
} DMAaddr;

static union {
signed int w; // One 16 bits words
signed char b[2]; // Two 8 bits bytes
} DMAcntr;

...

static void setadr( unsigned int far *buff, unsigned int length )
{
unsigned int lw;

  lw = FP_SEG( buff ); // Segment address of buffer
  DMAaddr.w[1] = ( lw >> 12 ) & 0xf; // Makes real 32bit address
  DMAaddr.w[0] = ( lw << 4 ) & 0xfff0;
  DMAaddr.l += ( unsigned long )FP_OFF( buff );
  DMAcntr.w = length;
}

Thanks,
mc303
