I was just trying to avoid derailing the discussion for finding an immediately good solution by searching for the perfect solution. Idiom finding simply is completely independend from the posed problem that Georg-Johann has, which remains unsolved AFAICS, as using fno-builtin-foobar has its own (perhaps mere theoretical for AVR) problems.
