  Are you trying to set the oscillator calibration register to some
  value you determined at compile time?

  If so, how about this code?
 
  #define CALIBRATION 0x10    // For example

  #include <avr/io.h>

  main () {
      outb(OSCCAL, CALIBRATION);
  }

  That sets the OSCCAL register in the processor to a value of 16.

  Is that what you are trying to do, or something else?
