[Rd] [R] Problem compiling in extra/xdr

[Prof Brian Ripley]

1) The current R-patched should compile src/extra/xdr on 32-bit Linux 
systems.

2) Longer-term or on a 64-bit platform the solution is to make use of 
libtirpc: you would need both this installed (common now) and its 
headers (unlikely).

Then if you arrange for /usr/include/tirpc to be in the C include path 
(not easy to do portably, but using C_INCLUDE_PATH will work on 
Linux), the tirpc versions should be found.
