Comment (by pbristow):

 I confirm that providing something to take the result of frexp works as
 predicted.

 T mantisssa = frexp(static_cast<guess_type>(x), &exponent);

 This provides an easy workaround for the current release 1.56.

 (But it is curious the GCC works OK without this when MSVC fails?).
