Combination of glibc 2.26-4 and gcc 7.2.0-3 produces of following
warnings at the compilation phase of rdma-core.
[24/189] Building C object librdmacm/CMakeFiles/rspreload.dir/preload.c.o
../librdmacm/preload.c:818:9: warning: no previous prototype for ‘readv’ [-Wmissing-prototypes]
ssize_t readv(int socket, const struct iovec *iov, int iovcnt)
^~~~~
../librdmacm/preload.c:857:9: warning: no previous prototype for ‘writev’ [-Wmissing-prototypes]
ssize_t writev(int socket, const struct iovec *iov, int iovcnt)
