Unable to understand this compiler error

[Lubos Pintes]

Interesting. In treeview module I mentioned, there is an enum containing 
some numeric values cast from HTREEITEM, which is in fact HANDLE, which 
is void* if I understand properly.
I tried to convert DGUI to use dsource' WindowsAPI project, and at least 
from compiler perspective, everything worked except this TreeView 
weirdness...
