Mine reports a creation time of May 11th 1998, but upon running `nm' I
see that it indeed exports those two functions, and a test program
compiled in MinGW:

  int
  main ()
  {
    extern int ShellExecuteW ();
    extern int SHFileOperationW ();
    char *x = (char *) &ShellExecuteW;
    char *y = (char *) &SHFileOperationW;
  }

starts and exits with no error dialog, and yet Emacs still does not link
if it imports either symbol.  Might there perhaps be symbol versioning
mechanisms or parameters in object files that influence its view of
external symbols?  I'm lost, sorry.

It resets numerous other variables and also initializes the "console
ctrl handler", which gave me plenty of pause.
