e3257cf: Build warnings

[tomreyn]

Hi,

after a long break, I finally had another look at GAE. While building e3257cf6375580745f9bc365bd842544f8907852 (on amd64), these (possibly intended and probably non-problematic) warnings showed up:

Yeah, one can say that they are "intended". It'll probably never happen that it reads less than it was told to read (size is small enough). So the return value is useless. One could still silence the warning though or really fix it...
