c: specify static array size in function params
The C standard states: A declaration of a parameter as ``array of type'' shall be adjusted to ``qualified pointer to type'', where the type qualifiers (if any) are those specified within the [ and ] of the array type derivation. If the keyword static also appears within the [ and ] of the array type derivation, then for each call to the function, the value of the corresponding actual argument shall provide access to the first element of an array with at least as many elements as specified by the size expression. By changing void func(int array[4]) to void func(int array[static 4]), we automatically get the compiler checking argument sizes for us, which is quite nice.
