How to compile in gtk+ 1.3

[Flávio Alberto Lopes Soares <flavio maqplas com br>]

Hello all,
I downloaded the GTK+ 1.3 (rpm packages) and make upgrade, aparently all
OK,
now I want to compile an aplication that I was making with gtk+1.2.10
(the interface was generated by Glade),
but it always compile in gtk+1.2, I see in Makefile that it make many
references to gtk+1.2, what I has to change to compile
in gtk+1.3 ?

Thanks in advance
