That won't compile, I think.

It's an internal function, and this patch is changing a bunch of
internal functions into returning -1 on failure ad 0 on success, which
is something vncviewer() is not doing.

It's not too big of a deal, honestly, and you can even let it alone
(we're not going to get 100% consistency anyway), but I thought you may
want to at least consider what to do.

OTOH, autoconnect_vncviewer() does have an _exit() that needs to be
dealt with.

Regards,
Dario
