No, because the block happens only if ${enable_flags_setting} == yes, and that can only occur if all CFLAGS/CXXFLAGS/CPPFLAGS/LDFLAGS are unset. If I do ./configure CFLAGS="-O2", the whole block won't be triggered (as intended). That block only exists to set defaults for users running ./configure without any of the aforementioned flags set, not for users overriding them.
