677319746 added support for making use of MSVC's bit scanning functions. However, that commit failed to consider 32-bit MSVC builds where the 64-bit versions of these functions are unavailable. This resulted in compilation failures on 32-bit MSVC. Here we adjust the code so we fall back on the manual way of finding the bit positions for 64-bit integers when building on 32-bit MSVC.
