Have a look at M-x find-function grep-find once, and see that it first
checks the value of `grep-find-command', and then uses it's own unique
`grep-find-history' variable for the command history.

You could create a ".dired" file for the top-level directory of you C
project with:

  Local Variables:
  grep-find-command: "find . -type f \( -name '*.[hcs]' -or -name '*.cpp' \) 
-print0 | xargs -0 -e grep -n -e "
  End:

That should make it do what you want by default whenever you run it from
that location, provided you have first requested a directory listing via
dired so that the .dired is seen.

You could also, if you liked, use `add-to-list' to push that string onto
the `grep-find-history' in ~/.emacs.
