Newbie GTK developer. Is GTK 1.1.12 compatible with GTK 1.0

[yusufg huge net]

Hi, I am interested in learning about GTK. From my limited knowledge
of GTK apps, I see most of them coded against GTK >= 1.1.6. I am on a
Redhat Linux 5.2 box which has gtk+-1.0.6-3 and gtk+-devel-1.0.6-3

If I download and install gtk 1.1.12, is it going to break existing
apps. What is the best way to develop apps using GTK >= 1.1.6 and yet
be able to use existing GTK apps on a RH 5.2 box

Thanks, Yusuf
