i don't want to steal your thunder or anything, but i thought this might
be amusing with respect to your 'nontrivial' comment.  of course, it assumes
you've got lex handy:

%{
/* this Lex script generates a filter that removes comments from C sources.
 * to compile:
 *	lex -t < {this text} > comments.c
 *	cc -o comments comments.c -ll
 * to use:
 *	comments < {C source} > {uncommented C source}
 */
