Answer 1

The copy on my system came from libxt-dev

$ locate Intrinsic
/usr/include/X11/Intrinsic.h
/usr/include/X11/IntrinsicI.h
/usr/include/X11/IntrinsicP.h

$ dpkg-query -S /usr/include/X11/Intrinsic.h 
libxt-dev:amd64: /usr/include/X11/Intrinsic.h

You may want to install and use apt-file - you can ask it for a filename and it will tell you which packages (that you don't even have to have installed - just from the repos in your sources.lists) contain a file with that name

Answer 2

I installed the libxt-dev package on my Debian box:

apt-get install libxt-dev

Then the proper header will be installed:

# find /usr -name "Intrinsic.h" -print
/usr/include/X11/Intrinsic.h

Been using xv for several decades now -- I always find myself trying to rebuild it.
