#1028 Incorrect VariantCopy declaration

[Nikita Leontiev]

VariantCopy declaration from oleauto.h (Windows SDK 10.0.26100.0):

WINOLEAUTAPI VariantCopy(_Inout_ VARIANTARG * pvargDest, _In_ const VARIANTARG * pvargSrc);

Second arg has const qualifier.
VariantCopy declaration from oleauto.h (mingw-w64 v14):

WINOLEAUTAPI VariantCopy(VARIANTARG *pvargDest,VARIANTARG *pvargSrc);

const qualifier missing for the second arg.
