That looks like a change in how the compiler treats bad code, or the
introduction of bad code in an updated version of Firefox. The
compiler can't sanely do pointer arithmetic without knowing the
pointer type. Looks like the version you're compiling with throws an
error on that.
Are using anything like -Werror and/or -Wall in your CFLAGS?
