### Check where struct rpcent is declared.
#
# This is necessary to determine:
# 1. If /usr/include/netdb.h declares struct rpcent
# 2. If /usr/include/rpc/netdb.h declares struct rpcent
#
# We have our own rpc/netdb.h, and if /usr/include/netdb.h includes
# rpc/netdb.h, then nastiness could happen.
#
# Logic: If /usr/include/netdb.h declares struct rpcent, then check
# rpc/netdb.h.  If /usr/include/rpc/netdb.h declares struct rpcent,
# then define STRUCT_RPCENT_IN_RPC_NETDB_H, otherwise do not.  If
# neither netdb.h nor rpc/netdb.h declares struct rpcent, then define
# STRUCT_RPCENT_IN_RPC_NETDB_H anyway.
