I see amd64 has given these warnings already in ELinks 0.11.3,
but there they didn't break the build, because configure was not
run with --enable-debug and so it did not add -Werror to $CFLAGS.
Please try the appended patch.
There has been a similar warning in src/network/ssl/socket.c, at
the gnutls_transport_set_ptr call. That could also be silenced
with an extra cast, but this would in principle also require
changing the code that converts the pointer back to an integer,
and I can't find where that happens, so I'm not changing it now.
Perhaps there is no such code and the call could just be removed.
