Compiling GTK+1.0* programs with GTK+1.1*

[Christophe "Histrion" GRAND <chr grand easynet fr>]

I have on my system (RH5.1, i386) Gnome 0.30 running
And i also have the following RPMs installed :
GTK+-1.1.2
GTK+-devel-1.1.2
GTK+10-1.0.6
glib-1.1.3
glib-devel-1.1.3
glib10-1.06
And when i try to compile the Gimp 1.0 now, i obtain this
error:

../gck/gcktypes.h:122: parse error before `GtkAcceleratorTable'
../gck/gcktypes.h:122: warning: no semicolon at end of struct or union
