Disable useless-cast warning for moc generated code
The useless-cast gcc warning is disabled in the files generated by
the moc. A typical warning is like
using_t = void(Counter::*)(int );
if (*reinterpret_cast<_t*>(_a[1]) ==
static_cast<_t>(&Counter::valueChanged)) {
*result = 0;
return;
}
Removing the static cast results in a compilation error
"address of overloaded function with no contextual type-of
information" in moc_myobject.cpp files.
Checking whether we have an overload set or a single function
might be too much effort for too little benefit and may not worth
it.
Fixes: QTBUG-71938
