Unittest `basicstuff` failing when CXX11 is enabled.
Just tried to run make check
on latest Eigen and it fails compiling basicstuff with the following error
call of overloaded 'complex(const Eigen::bfloat16&)' is ambiguous
385 | return static_cast<NewType>(x);

this fails to appear once you turn CXX11 off.
Tested on Intel and ppc64le.
