Surely, we have not made offer sufficient about x86_64.... However, The check of operation
was performed by the temporary rental machine. Moreover, there is also a situation of taking
time in the check of the present BIGENDIAN. Then, late work may be blamed....
Anyway, In order to avoid a problem, to be warning should clear.

BTW, FreeBSD x86 is this.
inet% gmake socket.o
gcc -DHAVE_CONFIG_H -I. -I. -I.   -I/usr/local/include -I/usr/local/pgsql/include -Wall -g -O2 
 -MT socket.o -MD -MP -MF ".deps/socket.Tpo" -c -o socket.o socket.c; \
then mv -f ".deps/socket.Tpo" ".deps/socket.Po"; else rm -f ".deps/socket.Tpo"; exit 1; fi
socket.c: In function `SOCK_wait_for_ready':
socket.c:468: warning: 'no_timeout' might be used uninitialized in this function
