--- Comment #3 from Florian Weimer <fw at gcc dot gnu.org> ---
Jan, do you actually experience a build failure? The part you quoted only shows
warnings.

Thomas, the safe thing to do would be to use __builtin_calloc and
__builtin_realloc in those spots because it avoids a dependency on an external
header that might not exist at this point.
