Building Scaffold

Hi, I am trying to build scaffold but I've encountered a problem:

window.c:69: parse error before "pixmaps"
window.c:69: warning: type defaults to `int' in declaration of `pixmaps'
window.c:70: warning: implicit declaration of function `GDL_PIXMAP'
window.c:70: initializer element is not constant
window.c:70: (near initialization for `pixmaps[0]')
window.c:72: `GDL_PIXMAP_END' undeclared here (not in a function)
window.c:72: initializer element is not constant
window.c:72: (near initialization for `pixmaps[1]')
window.c:72: warning: data definition has no type or storage class
window.c: In function `scaffold_window_instance_init':
window.c:552: warning: implicit declaration of function

make[2]: *** [window.o] Error 1
make[2]: Leaving directory `/usr/src/scaffold/src'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/usr/src/scaffold'
make: *** [all] Error 2

What am I doing wrong? I've just Checked it out from the gnome cvs
server... :(
