One of my friends said that git is not working for their development
model... C++ development with static linking across the board, where
they need to see exactly which version of the file has got to the
executable. Roughly, they are using CVS' keywords and revision numbers
and a script wich matches them between two versions of the
executables.

I've got curious if Git can support it and how it can be done with
minimal changes to workflow.

If the project is already arranged to be compiled with decent automation,
I do not think you need any change to the workflow.

You would have a version.cc file with

	static char program_version[] = "My Program " VERSION_STRING;

in it, and teach the build procedure how to compile and link this file.
Something like:

    version.o: version.cc
    	$(CXX) -o $@ -DVERSION_STRING=\""$(git describe HEAD)"\" $?
