ok, i get it somehow:

dv1394.h does not define any interfaces to library-bindings.
it merely defines one or 2 structures and a number of ioctl()-commands.
since this is really an implementation detail of the kernel-driver, i 
understand why it has been deprecated by libdv.

i have checked a version of videoDV4L into the CVS that uses the 
header-file from the kernel. (some changes where necessary, as they have 
changed the ioctl-commands from DV1394_ to DV1394_IOC_)
the videoDV4L.h therefore includes <ieee1394/dv1394.h>; so you have to 
add /usr/src/linux/drivers to the include-path
is this the correct way to do it ???
or rather include <dv1394.h> and add /usr/src/linux/drivers/ieee1394 (or 
whatever)

so we just have to force people to have kernel-headers installed.
i think we can assume, that most linux will have the current 
kernel-headers in /usr/src/linux (?)

ok.
i sometimes need to disable things, just for testing...
