Okay, the shortest test program is the following:

#include <stdlib.h>
#include <stdio.h>

#include "allegro.h"

int main()
{
  int c;

  allegro_init();
  install_timer();
  do
  {
    c = getch();
    rest(1000);
    while (kbhit())
      c = getch();
  }
  while (c != 27);
}

It basically does the same that happens in a game loop, but doesn't work
(When I press a button for a longer time, I hear a loud beeping, which
means, that the kb-buffer is full, right?)
