I think djgpp comes with the very nice utility `sed'. With the following 
script you can remove C-comments. (You do very, very much more though)
---8<---
#!/usr/bin/sed -f
# Strip comments from C source.
# Carlos J.Duarte

# if no /* get next
/\/\*/!b

# here we've got an /*, append lines until get the corresponding
# */
:x
/\*\//!{
N
bx
}

# delete /*...*/
s/\/\*.*\*\///
:t
/^$/d
---8<---

This was written for unix/linux but can easily be ported to dos.

(yes it looks like junk)
