Maybe you can write 2 different callbacks, one with if, one

I like that idea.  But it is less elegant.  For example, for a 
timer callback, I may have to restart the timer with a new 
callback function.  Instead of a single callback, if it is a 
event subscription, other subscribers will be affected.

Maybe with a compile-time code generation to avoid code 
repetitions...

I am looking for a more generic solution.  It should work with 
within a loop also.  Just for the sake of achieving it I will 
have to put those statements in a function, call it with function 
pointer, etc.

while(true)
{
   ...
   Statement_1;
   if(i == MY_MAGIC_NUMBER)
   {
      //done with this.
   }
   Statement_3;
   ...
}

Just for a int comparison or is it a different long operation?
:)  you will ask me to short cut with a simple condition.
