No you don't. But you *do* need real regex matching (as in, not just a
per-line matching), which is provided by flex. Probably why flex is a good
choice for this. The following (extended) regex should work:
\/\*([^*]|\*[^/])*\*\/
However, if you it with grep it won't work, because grep is line-based,
and this will fail to catch multi-line comments. It is probably possible
to write a sed script that does this---sed is also line-based but it can
keep state, so you can work around the limitation.
