Subject: [PATCH] drop explicit check for EWOULDBLOCK if it has the same value
 as EAGAIN

gcc correctly reports that we check for the same value twice, expect
that the manpage of read(2) tells us to do it for portability, so to
make both sides happy lets add a little #if'ing here.

Reported-By: gcc-6
