Ah, a fellow clean-compile enthusiast (or security minded individual). Actually, we (I) treat a clean compile is a security gate. If the code can't clean compile, it does not meet quality standards and gets kicked until it can.
You might want to to try -Wall -Wextra -Wformat=2 -Wformat-security -Woverloaded-virtual -Wreorder -Wno-unused -Wno-type-limits. The last three ease the use of C++ with -Wall -Wextra. For linker hardening, try -z relro and -z now for PLT and GOT attacks.
