Bug ID: 56692
           Summary: Wine-staging "new WoW64" build fails in Fedora 40
           Product: Wine-staging
           Version: 9.8
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]

      Distribution: ---

The OBS has not enabled i586 builds for Fedora 40, so I created spec files to
do "new WoW64" builds. The wine-devel packages built fine, but the wine-staging
build failed with:
> [  392s] dlls/combase/string.c: In function 'impl_from_HSTRING_BUFFER':
> [  392s] include/winnt.h:888:46: error: initialization of 'const WCHAR (*)[1]' {aka 'const short unsigned int (*)[1]'} from incompatible pointer type 'HSTRING_BUFFER' {aka 'struct HSTRING_BUFFER__ *'} [-Wincompatible-pointer-types]
> [  392s]   888 |    const typeof(((type *)0)->field) *__ptr = (address); \

In Fedora 39, that's a warning, not an error, and the build succeeds.
