Hello Aron, -O0 is still used with my patch because later optimization flags override previous ones. Hardening flags shouldn't make debugging more difficult because no unfriendly optimizations take place and if -dbg and non-debug package are built with the same flags no unexpected behavioral changes happen (e.g. crash in non-debug package because stack-protector is used but no crash in -dbg package; one exception are the CPPFLAGS which are disabled with -O0). And using hardening flags for the complete package make automatic checks for missing flags (e.g. blhc) possible.
