MFC r229590 manually:

  It turns out our GCC has quite an interesting bug:

        typeof(1.0fi) != float _Complex
        typeof((float _Complex)1.0fi) != float _Complex
        typeof((float _Complex)1.0i) == float _Complex

  In other words: if casting to an equal size, GCC seems to take a
  shortcut. By casting down from a double to a float, GCC doesn't take
  this shortcut, yielding the proper type.
