Subject: [PATCH] Remove all initializers from static loader arrays

C standard gives guarantee they will be NULLed by default:
https://port70.net/~nsz/c/c89/c89-draft.html#3.5.7

>  If an object that has static storage duration is not initialized explicitly, it is initialized implicitly as if every member that has arithmetic type were assigned 0 and every member that has pointer type were assigned a null pointer constant. If an object that has automatic storage duration is not initialized explicitly, its value is indeterminate.
