To be clear, these libraries are bundled with Samba, the error is not
fatal, we just use the system one if is is recent enough. 

I think the real error here comes from the old C compiler not liking
something that rpcgen, an xDR compiler, generates.  

Clearly Samba 4.9 is no longer compatible with this old system, or
rpcgen is not installed.  

If the error is the latter, a configure test would be grand, to error
out during configure.

I hope this clarifies things,
