Finally I found the problem, this occurs at function GSPrivateLoadModule() in objc-load.m. The problem is the NSString method -fileSystemRepresentation, that returns a 16-bit unicode string. The function dlopen() on mingw don't support this. So I solved the problem just using -UTF8String and now backend works again.
