This patch is difficult for me to handle, because I don't know which
patches it fixes - probably it fixes two separate ones and needs to become
two patches. Usually it's obvious which patches are being fixed.
Sometimes reporters will tell me which patch is being fixed (extra nice!).
In this case, it's unobvious.
Please always include the text of the error messages when fixing compile
errors.
Please send me the .config.
