Loading 2.6 symbols when linked against 2.4

[Ian King <king eiffel com>]

Hi,

Our application is linked against gtk 2.4, however we would like to be 
able to call functions from gtk 2.6 if they are available on the system 
(for things such as text ellipsis rendering from pango).  Can gmodule be 
used for loading these functions and has anyone done this successfully?

Thanks for your time
