### 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
