That's a bug in your rpc.h header, and not in libvirt proper.  Slackware
is not the only platform with this problem; compiling libvirt on cygwin
hits the same issue.

The message is only a warning, so you may safely ignore it.

That's a bit tougher.  I thought we had code in place to try to
guarantee that we could find a 64-bit unsigned converter across the
various flavors of RPC, but apparently we aren't configuring it
correctly.  Can you look in your /usr/include/rpc/xdr.h, and see what
functions might be available?  For example, other known spellings have
been xdr_u_hyper, xdr_u_quad_t, or xdr_u_int64_t; if we can determine
what name to check for in configure.ac (we're currently checking for
xdr_u_int64_t), then we can patch src/remote/remote_protocol.x to honor
that alternate spelling.
