C++ source code

I just tried to compile the package berusky2-0.5-1
on latest trunk dated 20111208 on an AMD x86_64 box.

The compiler said

age/graph/animation_track_bezier.cpp: In member function 'WVECT*
anim_track_bez_wvect::tangent(int, BEZIER_KEY_CLASS, WVECT*)':
age/graph/animation_track_bezier.cpp:446:9: error: invalid types in conversion
to floating point
vector(4) float
vector(4) FERGUSON_KEY_CLASS
vect_var_.776_404 = (vector(4) float) vect_cst_.777_403;

age/graph/animation_track_bezier.cpp:446:9: internal compiler error:
