Hi! As reported in the PR, since special_fname_builtin () call has been introduced, the diagnostics code compares filename against _("<built-in>") rather than "<built-in>", which means that if self tests are performed with the string being translated, one self-test fails. The following patch fixes that.
Bootstrapped/regtested on x86_64-linux and i686-linux (with normal C locale) and by the reporter in German, where it fixes the problem.
