[PATCH] This fixes a bug in POSIX-compliant environments. Since we had allocated a buffer named 'tcg-jit' with read-write access protections we need a int type to combine these access flags and return it, whereas we had inexplicably return a bool type. It may cause an unnecessary protection change in tcg_region_init().
