Changed formula for getting the number of elements in a static array

Browse Source 
When using the formula [sizeof(array) / sizeof( x )] to get the number
of element in a static array, it is better to use array[0] for 'x'
instead of the base type of array:
 - in case the base type would change someday;
 - if the compiler were deciding to insert padding somewhere
