32-bit dlls in 64-bit process

[Viktor Semykin]

Hello.

I'm trying to run Adobe Photoshop Lightroom using Wine. One of the 
showstoppers was the fact that 64-bit process of Lightroom is loading 
32-bit DLLs containing various resources. While Windows allows it [1 
https://support.microsoft.com/en-us/help/282423/list-of-limitations-in-64-bit-windows] 
wine does not.

I made this simple change to Wine code just to make it work for my local 
usecase:
> --- a/server/mapping.c
> +++ b/server/mapping.c
> @@ -414,8 +414,6 @@ static unsigned int get_image_params( struct

> return STATUS_INVALID_IMAGE_FORMAT;
>          break;
>      case CPU_x86_64:

>      case CPU_POWERPC:
>          if (nt.FileHeader.Machine != IMAGE_FILE_MACHINE_POWERPC) 
> return STATUS_INVALID_IMAGE_FORMAT;

From what I can tell this change looks neigher neat nor correct.

My question is, what is /the/ correct way to allow loading 32-bit dll 
into 64-bit process just for loading its resources.

Thank you.
