That is not possible. The gtk2 unit is already delivered precompiled with
a release. So it can't detect the gtk version installed at your machine.

The only possible solution i see is to add multiple units gtk2_2, gtk2_4
and gtk2_6 that provide the functions for each gtk release. But that needs
to be decided with the original gtk2 for pascal maintainers.
