--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
This is a longstanding issue that glibc headers expose all APIs when includ=
ed
from C++ code.

You can either cast the function pointer to the right type:

    std::sort(ptr, ptr, static_cast<bool(*)(foo, foo)>(bcmp));

or use a lambda expression:

    std::sort(ptr, ptr, [](foo l, foo r) { return bcmp(l, r); });
