I know this is slightly off the point, but I feel the need to plug the book
that covers this topic better than any other I've heard of.

The O'Reilly book, Mastering Regular Expressions, has extensive coverage of
this issue. The chapter that dives into the idiosyncrasies of Perl has a
section, "Removing C Comments", that sums up the previous remarks with what
it calls a "crisp solution" for this specific application.
