[Users] XMPP module: network.c file error

[isetien001 at ikasle.ehu.es]

Hi!

I'm trying to make xmpp module, to do this I'm configurating according
to my file system several files (xmpp_component.c, util.c, xmpp.c ...).
But I get error while compiling the file 'network.c'.

I don't know where these errors come from because the rest of the files
are OK.

These are the errors and my 'network.c' file:

Any help would be wellcomed.

Izortze.
