/* 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.
