Ok,

I try a little trick:

in gdm-server.c and gdm-x-session.c, I remove the conditional if:

#ifdef HAVE_XSERVER_THAT_DEFAULTS_TO_LOCAL_ONLY (and corresponding #else 
and #endif), leaving the remaining code.

I compile the code and now I have the "-listen tcp"  in command line.

So the problem certainly come from the 
HAVE_XSERVER_THAT_DEFAULTS_TO_LOCAL_ONLY condition.

Cheers
