PVS-Studio warning V801 for Ultimate ToolBox

BOOL operator==(const _tagMODULEINFO mi) const
{
 return ((hModule==mi.hModule)&
   (sModuleFileName.CompareNoCase(mi.sModuleFileName)==0));
}

This code doesn't contain errors, but it can be made more efficient. There's no need in creating a copy of the _tagMODULEINFO structure each time when calling the '==' operator. The V801 message points out that "const _tagMODULEINFO mi" can be replaced with "const _tagMODULEINFO &mi".

This suspicious code was found in Ultimate ToolBox project by PVS-Studio static code analyzer.
Warning message is:
V801 Decreased performance. It is better to redefine the first function argument as a reference. Consider replacing 'const .. mi' with 'const .. &mi'. UT oxdllmanager.h 123
