min version for GtkItemFactory?

[Allin Cottrell <cottrell ricardo ecn wfu edu>]

I've written a little app that uses the item factory.  It
compiles fine against gtk 1.2.1, but it failed when I tried on
another machine with gtk 1.0.6.  I infer that the item factory
must have come into existence somewhere between those version
numbers.  Can anyone tell me when?

Also, can anyone point me to a newbies guide to what should be
put into configure.in to test for a given minimum version of
gtk?  Thanks very much.
