Visual C++ Compiler Warning C4187

Message Text

#directive attributes 'attribute1' and 'attribute2' are incompatible; both ignored

Circumstances

The directive is necessarily import. The incompatible attributes are

• dual_interfaces and no_dual_interfaces
• function_mapping and no_function_mapping
• implementation_only and no_implementation.

For who can imagine what reason, the product documentation mentions only the last pair.
