// We use the #pragma to avoid a compiler warning about incompatible
// pointer types, because we generate code passing a struct ptr rather
// than using the typedef. This warning is expected and does not break
// a normal build.
// We can only disable -Wincompatible-pointer-types starting with GCC 5.
