<div>
<pre>In the lzcntintrin.h, the 32-bit version of lzcnt should be named __lzcnt(),
not __lzcnt32().
This causes linker errors when compiling with ms compatibility because the
correct prototype is in intrin.h:
unsigned int __lzcnt(unsigned int);
See <a href="https://docs.microsoft.com/en-us/cpp/intrinsics/lzcnt16-lzcnt-lzcnt64">https://docs.microsoft.com/en-us/cpp/intrinsics/lzcnt16-lzcnt-lzcnt64</a> for
reference.</pre>
