I ran into this trying out dmd 2.063 : 64 bit, these functions are still missing win64.  Looking at math.d it appears the following are definitely missing in the version wrapped by 'DigitalMarsWin64':

isfinite
isinf
isnormal
signbit
fpclassify

Since Visual Studio 2013, those currently disabled functions, nearbyint(), lround(), remquo() and also remainder() have been potentially available.

In addition, because newer runtime libs are shipped with compiler packages nowadays, basically no need to consider link errors due to missing functions.

It's a good time to unbind them.
