All,
I'm sure there is a reason why utils.c isn't using the getservent/getprotoent services from netdb.h - maybe platform related ? I don't know - but here is a patch that 1) uses those services for accessing /etc/protocols and /etc/services, and thereby fixes the minor problem with comments in either file. At least it works on Linux.
