[Xcb] Problems with xcb_atom_get()

[comick]

I can't use xcb_atom_get() inside my code.
Obviously o give the output of `pkg-config ... xcb-atom ....` to the linker, 
but I receive:

	undefined reference to `xcb_atom_get(xcb_connection_t*, char const*)'

any way. I'm using xcb-util 0.3.3 from Debian testing packages. Other xcb-
utils libraries works fine.

Thanks.
