[PATCH] xdr.3: SYNOPSIS: Fix prototype types

[Alejandro Colomar <alx.manpages@gmail.com>]

Use the same types glibc uses, and add a missing 'const'.

.../glibc$ grep_glibc_prototype xdr_union
sunrpc/rpc/xdr.h:315:
extern bool_t xdr_union (XDR *__xdrs, enum_t *__dscmp, char *__unp,
			 const struct xdr_discrim *__choices,
			 xdrproc_t __dfault) __THROW;
.../glibc$
