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.
