+#### Description
+
+The compiler(msvc) reports error: `..iqk_quantize.cpp(568,12): error C2668: "'anonymous-namespace'::hsum_float_4”: 对重载函数的调用不明确..` , I found some functions defined repeatedly and move these to `iqk_common.h`, It can be compiled successfully, but on linux doesn't seem to get the error...
