    Description

      Check nr in the code below is POSIX read api semantics but is wrong for Windows. This causes the WIndows code to lose error information if read fails.

                      if (!ReadFile(fh->filehandle, addr, chunk, &nr, &overlapped))
      		 
                              WT_RET_MSG(session,
      		 
                                 nr == 0 ? WT_ERROR : __wt_getlasterror(),
      		 
                                  "%s: handle-read: ReadFile: failed to read %lu "
