The code of CFLOW is here:
http://packages.qa.debian.org/c/cflow.html
(get the original package and the patches)

As a dependency also get:
http://packages.debian.org/stable/base/debianutils.html
(you need to install only 'tempfile' from that package as far as I remember).

Then run 
cflow file.c

Thanks for the hint, Roger,
