Takashi, do you have any comments on this patch?
Sorry for the late reply. Yes, I already applied it weeks ago, but the reply mail wasn't sent out but stuck in my output queue by some reason during my vacation.
Anyway, thanks for the patch. I think it's OK in the way you did for the time being. Ideally, read*_be() should be defined on all platforms, though.

Thanks!
If the platform already provides a definition for these accessors do not redefine them. The warning was caught on MIPS.
