New Revision: 311947
URL: https://svnweb.freebsd.org/changeset/base/311947

Log:
  rpcgen(1): Avoid unused variable warning on generated code.
  
  Avoid "unused variable 'i'" warnings in generated .c files by only
  emitting the "int i;" for non-opaque arrays. Opaque arrays use
  xdr_opaque() rather than iterating over the array.
  
  Obtained from:	OpenBSD (CVS rev 1.28)
