Bootstrap-O3 complains about uninitialized uses of this variable in gengtype-state.c. The variable can never actually be used before initialization, but GCC is not smart enough to realize that. read_state_structures, just before the function at hand, has a similar loop and it zero-initializes both head and previous, so I adjusted the affected function to follow the same pattern and avoid the bogus warning. Regstrapped on x86_64-linux-gnu and i686-pc-linux-gnu. Ok to install?
