libc warnings/fix

[Alexander Shishkin <alexander.shishkin@xxxxxxxxxx>]

Hi,

I have one more patch [1] to fix three "may be used uninitialized in this
function" warnings emitted by newer gcc. All three are unlikely to cause
any problems [obviously], but are perfectly valid from compiler's
standpoint.
