Anything grep that come with anything-config.el allow you to do that in
two ways:

1) If you want to do a recursive search from your directory, access grep
with C-u, you will be prompted with "OnlyExt: ", add all the ext you
want like:
*.c *.h *.cpp
(separated with space)

2) if you don't want to recurse, from anything-find-files, narrow dow
the list in your directory by adding a space followed by c$\|h$\|cpp$ at
end of prompt e.g
Pattern: /home/you/work/ c$\|h$\|cpp$

then select grep (no prefix arg this time) and start writting your
pattern.

FYI, this grep is incremental, results changes as you write in minibuffer.

NOTE: You DON'T need the file anything-grep.el that is in anything repo,
this work out of the box with the files:

anything.el
anything-config.el
anything-match-plugin.el

Here is the anything repo:
http://repo.or.cz/w/anything-config.git
