Description:
------------
Good morning,

Re. php-5.0.0   

I noticed in sunfuncs.c/php_sunrise_sunset() there's this commented out
snippet:

  /* XXX: What's the use of this block.. ?
   * if (!calc_sunset && cosH > 1 || calc_sunset && cosH < -1) {
   *    throw doesnthappen(); 
   * }
   */ 

What the 'if' clause actually would detect is cases where you have no
sunrise or sunset, i.e. during the midnight sun period, on the Northern
hemisphere around June 21st, above ca. 66.5 deg latitude.        

For instance, try:

        php_sunrise_sunset( 182, 66, 0, 90.83, 0 );

this should give a good value for sunrise, very early in the morning.

Now try
       
        php_sunrise_sunset( 182, 67, 0, 90.83, 0 );

this should give NaN.

The reason is obvious: above ca. 66.56 deg latitude in the summer (here
day 182) you have the midnight sun period: the sun doesn't set and/or
rise.

However, this function isn't used anywhere -- is it?
