[Yaffs] YAFFS compilation warnings

I'm in the middle of tracking down a bizarre single bit flipping error that
seems to be related to the name of the file that I am trying to create and I'd
like to make sure that my YAFFS is compiling correctly.

I get these warnings when I compile my kernel, can someone verify that these
are OK?

I'm using latest MTD, latest YAFFS and 2.4.27-vrs1.
