--- Comment #1 from Georg-Johann Lay <gjl at gcc dot gnu.org> --- A native build on x86_64 produces warnings about avr documentation.(In reply to David Binderman from comment #0) > A native build on x86_64 produces warnings about avr documentation. This is an issue in the texinfo software that has been fixed. The @anchor's are in a legal location, but affected versions of texinfo produce an incorrect warning (though the generated code is correct). See for example this thread with an approval of respective texinfo patch: https://lists.nongnu.org/archive/html/help-texinfo/2023-11/msg00004.html So I think this is invalid as a GCC PR. When you are annoyed by that warning, use a texinfo version with a fix.
