that'd be great. This log contains how the configure script thinks that
doubles can be converted to the x86 representation, which is the
representation used in the network protocol. You can look for the string

  checking if doubles are stored in x86 representation

which *should* result in "no" on SPARC and in "yes" on x86 and x86_64.

For SPARC I think the following test,

  checking if endianflip converts to x86 representation

should result in "yes".

I was hoping to see in what way the doubles are present in the network
packets. For this, I'd need a binary "PCAP" file containing the captured
packets in their entirety. The following command should capture 20
collectd packets sent from host "xxx" and store them in the file
"/tmp/collectd.pcap" (interface eth0 is assumed):

  tcpdump -c 20 -i eth0 -s 0 -w /tmp/collectd.pcap host xxx and port 25826

The "-s 0" option instructs tcpdump to not truncate packets, which will
happen if the option is not specified.
