Bug ID: 44699
           Summary: Clang 6.0 fails to run under wine
           Product: Wine
           Version: 3.0
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: advapi32
          Assignee: [e-mail]

This is the current output when running clang under wine.

```
fixme:file:FindFirstFileExW flags not implemented 0x00000002
fixme:file:FindFirstFileExW flags not implemented 0x00000002

fixme:crypt:CRYPT_LoadProvider Failed to load dll
L"C:\windows\system32\rsaenh.dll"
LLVM ERROR: Could not acquire a cryptographic context: Unknown error
(0x8009001D)
```

Here is the line it currently fails on.

This could be possibly related to #44061

To reproduce this you can run the following docker build script which build
llvm and clang and then cross compiles it for windows with mingw-w64.
Executing the resulting clang on a simple c source file results in the error.

This is an x64 application.
