    Description

      msvc14.3-amd64-Release build fails (on GitHub):

      MSVC 19.32
      		 
       
      		 
      ...\sdk\include\crt\math.h(298): error C2169: 'log2': intrinsic function, cannot be defined

      NB:
      I did not try ARM64.

      The C standard library functions log2 and log2f have been implemented as compiler intrinsic functions on x64 and ARM64. This allows the compiler to perform optimizations with log2 and log2f under /fp:fast x64 and ARM64.
