Re: [DynInst_API:] dyninst does not build with Fedora 28 glibc

[Jeff Hollingsworth <hollings@xxxxxxx>]

I am not sure XDR was ever used in Dyninst proper. XDR was used decades 
ago in Paradyn to communicate with external visualization modules.ÂÂ It 
may have ended up in Dyninst since XDR was one of the target 
communication modes of the igen interface generator (in addition to some 
faster native methods used for thread to thread communication).

Any RPCs we're performing should happen through ProcControl's RPC interface these days. (And by "these days" I mean roughly post-2010. I don't know how far back that code dates, but it's older than that I'm pretty sure.)
