Many people do a lot of rewriting when they port, which I would
consider a mistake.

Modulo the documented issues in the ref. manual
(http://developer.gnome.org/doc/API/2.0/gtk/gtk-changes-2-0.html) not
much should _break_ when you just rebuild with 2.0. 

However, many people rewrite GtkCTree code to use GtkTreeView, which
can be a lot of work, for example. Such rewrites are optional and can
be done in a later phase after the initial port.

There's often a better way to do something with 2.0 than there was
with 1.2, but the old way typically still works.
