+/* Hack for MinGW-w64 headers.
+ *
+ * We want to use WIDL C inline wrappers because some methods
+ * in D3D12 interfaces return aggregate objects. Unfortunately,
+ * WIDL C inline wrappers are broken when used with MinGW-w64
+ * headers because FORCEINLINE expands to extern inline
+ * which leads to the "multiple storage classes in declaration
+ * specifiers" compiler error.
