You can also try this:

#include <allegro.h>

volatile unsigned int counter=0;

void timer_handler(void)
{
 counter++;
}
END_OF_FUNCTION(timer_handler);

int main(void)
{
 unsigned int i;

 install_timer();
 LOCK_VARIABLE(counter);
 LOCK_FUNCTION(timer_handler);
 install_int(timer_handler, 1);  //1 is milliseconds between ticks

 .
 .
 Here is your code; like this
 i=counter;
 do
 {
  Blah();
  Blah();
 }while(counter-i<100);
 .
 .

 //no need to call remove_int(...), automatically called at exit
}
