That error message sounds like the lack of #include <qfloat16.h> may be
relevant.  There is a non-explicit qfloat16(float) constructor, which I
would expect to make that work, if its declaration were visible.

The code there is snippets; I wouldn't be at all surprised if what's
changed is that someone has enabled compilation of them as part of
normal builds, since that change integrated.

        Eddy.
