Hmm, when the second argument is omitted, the system call looks like:

getservbyname("daytime", NULL);

Based on "man getservbyname" on my Linux PC, that should give the behaviour we 
want - any protocol will match.

However:

Linux 2.6.4-52-default (Suse 9.1)
Glibc 2.3.3
gcc   3.3.3

So it may be that your older platform doesn't have this behaviour - I'd be very 
interested in what 'man getservbyname' has to say.

Cheers,
Nick.
