Arggh! No, please don't. Initialising it gives the impression that its value
is going to be used, but it is not, it's going to get assigned through an
output parameter of a function call.
That particular warning of GCC 4.0.1 is simply unsuitable for use with our
code. Disable it.
Please revert this commit.
(One thing this review showed me is that many of the functions that initialise
these variables, via non-const pointer arguments, are undocumented or poorly
documented.)

(It's not clear to me what's going on in this particular case.)

(Here you left in a redundant subsequent initialisation of "tunnel_argv".)

Here you can see an inconsistency: there are several other variables used there
in exactly the same way which you haven't initialised, presumably because GCC
hasn't complained about them for some reason.
