During compilation I see a lot of warnings: They are in pretty much 
every .../.../xyz.h file, the warnings are about variables that are set 
but not used. Perhaps this is normal. Then when things start to go 
haywire it begins with a couple of LDs on drivers/video/fb.o 
.../built-in.o and vmlinux.o followed by the command MODPOST that gives 
a warning that it found 10 section mismatches. It suggested that I 
should make with 'CONFIG_DEBUG_SECTION_MISMATCH=y' option/argument added.

Then the final straw that breaks it all is when line 28 in 
Documentation/video4linux/v4lgrab.c refers to linux/videodev.h that 
doesn't exist which terminates the compilation.

The cause of this seems to be that (according to an ubuntu bug report) 
the V4L1 API was removed in one of the Linux 2.6.38 pre-releases since 
v4l support has been dropped since kernel 2.6.35, and the 
<linux/videodev.h> header doesn't exist. Perhaps it compiles 
mediastreamer2/src/msv4l.c if either V4L1 or V4L2 is detected, and that 
file unconditionally includes <linux/videodev.h>.
