- Standard_EXPORT which were specified for inline methods were deleted. - ALL occurrences of DEFINE_STANDARD_RTTI_INLINE were replaced by DEFINE_STANDARD_RTTIEXT in header files and IMPLEMENT_STANDARD_RTTIEXT in source files - ALL occurrences of "inline" keyword were deleted where it didn't not cause a linkage errors - Added source files for classes that were without them for IMPLEMENT_STANDARD_RTTIEXT
