Patchset:

PS1: 
Our <symbols.h> intentionally declares memlayout symbol variables this way so they can be used like they were pointers without extra ampersands and indices. I'd prefer to keep it that way (because it's more readable and easier to write), so I think the better option here is to just add -Wno-array-compare to CFLAGS_common.
