For some reason muirct.exe is aware of the opaque structure used by BeginUpdateResource, it access the filename field of the opaque structure during it's processing.

The utility muirct.exe for some reason accesses the opaque HANDLE that is returned by BeginUpdateResource, it assumes a certain structure in which (on 32bit systems) there is a pointer to the wide repesentation of the file name in offset 0x18.

It'd be cleaner to use pointer-sized fields here.
More importantly, patch 1/2 will introduce failing tests, that normally should be marked with todo_wine, and you'd remove such marks in patch 2/2. In this case it's easier to simply send patches in opposite order, because failing test will be reading fields from incompatible data structure.

It's better to introduce a structure type instead, similar to what implementation is using.

Test function should be named in a more generic manner, after fixed functionality, not the application that's using it.
