Thanks for all those who replied. I got two free packages for my two
queries: one RPC to interoperate with existing C RPC programs and one
completely new and purely Ada. Here is a summary:

David Emery <emery@d74sun.mitre.org> sent me a short set of packages
("no warranty") to interface Ada with Sun's RPC (also called ONC) for
the Verdix compiler (but it should be easily adapted). This is a rather
thin binding. It seems to be able to interoperate with C programs.
Unfortunately, I wasn't able yet to compile it. May be Verdix changed
the appendix F?

Steve Case <scase@planet8.sp.unisys.com> developed an Ada interface to
XDR, Sun's library to deal with data format problems, a layer under the
RPC. I didn't test it. There is another XDR binding with the previous software.

Karl A. Nyberg <karl@grebyn.com> and William M. Hodges
<hodges@stars.boeing.com> pointed me toward SA-E's RPC, a free toolkit
to write RPC with Ada. I didn't try it yet, but it's well documented.

and, as you saw on this newsgroup, Bob Kitzberger <rlk@VisiCom.COM>
indicated that TeleSoft has an implementation of RPC. I don't know yet
if it can interoperate with programs written with other languages/compilers.

Time to launch another thread: should an Ada RPC be compliant with
existing RPCs (and, in this case, should it be implemented by a binding
or a rewriting?) or should it be a completely new system?
