This is just another way to say: "leave this code out". It usually is
cruft or stuff that was rewritten and left in as a reference in case
there are bugs in the new code. Sometimes (in rare cases) it's code
that is not ready yet.

This is a define that comes straight from the configure script. It
checks if we build on a rpm system (like connectiva or RH) and set
HAVE_RPM if this is the case.

This is from configure as well. You can call configure with
"--with-zvt". This will tell configure to look for libzvt from
gnome. This is terminal emulation widget so that we can show the
output of the package manager directly in a subwindow of synaptic. 


I hope this helps :)
