a sed and regex question

Hi,
I am generating some dependency files from gcc -MM.

Code:

---

Makefile.depend: *.h *.cc Makefile
    $(CXX) -MM $(CXXFLAGS) *.cc > Makefile.depend

---

Each rule in the resulted file is like:

Quote:

---

main.o : main.cc defs.h \
src/misc.h

---

I want to specify the directory where the object files will be put, i.e.

Quote:

---

$(BIN_DIR)main.o : main.cc defs.h \
src/misc.h

---

How to accomplish by using sed?

Note that I am not considering specifying the directories of source but the ones of object files.

Thanks and regards!

You can have/use this if you'd like.

EDIT: I removed this, then put it back up. For a brief moment, I thought I hadn't cleansed it of proprietary data.
