[libgnomecanvas] v2.0.X Strange error

Hi coders,

I try to compile the gnome_2 sources on a linux-k6 box. I compile all
libs without any errors, excepted the libgnomecanvas, I have tried with
both v2.0.0 and 2.0.1.

The configure process does not report any missing lib, however "make"
fails and returns unknown  typedefs.

I have grep'ed my whole system without any reference to them. My RedHat
is 7.1, brand new system without any gnome/kde existing package. I
compile with gcc 2.96 on an i586.

Thanks for any help,

Fred
