The dlls are quite fake. Even the larger ones contain no export table and a miniscule 5 bytes of code. But they do contain resources, that is icons.

Code:
winedump user32.dll
  size of code                       0x5            5
...
Data Directory
  EXPORT       rva: 0x0         size: 0x0
...
  RESOURCE     rva: 0x3000      size: 0x11bcc


That said, it is kind of a mystery why winecfg will not run when you replace certain fake DLLs. Is there some kind of automatic override going on?
My suggestion is don't put dlls into system32. Take only the dlls you need to override and put them into the individual program's folder.

There's lots of links about wine's fake dlls. Here's a couple I found.
