Upgrading from GTK+ 1.2 to 2.4

["Matthew Yaconis" <myaconis nycap rr com>]

I have an application that I am trying to "upgrade" to 2.4 from 1.2.  What is the best way to disable 
depreciated widgets?  My application uses several CLists and some option menus and I'd like my code to break 
when compiling.  I found that adding the #define "GDK_DISABLE_DEPRECIATED" is supposed to do the trick but it 
doesn't seem to work as I'd expect.  (I.e. everything still compiles with no warnings or anything.)

Any ideas or places in the manual to point me to?
