This and above are fine.

This is a different kind of warning. It is due to a compiler
false-positive (I'm guessing that you are seeing a warning about
uninitialized use of saved_errno, even though use of that variable is
properly gated so that it is initialized on all paths where it is later
used). But still okay, although I might have split it into a different
patch, and listed the compiler warning that it silences as part of the
commit message.

Here, I'd rather mark binpath as ATTRIBUTE_UNUSED than add the #else
preprocessor conditional. That is, ATTRIBUTE_UNUSED means only that the
variable might be unused, not that it can't be used (so used on linux,
unused otherwise qualifies).
ACK with that nit fixed.
