True.  A sharp is the comment indicator (left side) for m4.

This can be easily changed with changecom() to disable comments, or
something like changecom(/*,*/).

Try this:

m4<<!
define(xyzzy,plugh)
the magic word is xyzzy
the magic word is # xyzzy
changecom(/*,*/)
the magic word is # xyzzy
the magic word is /* xyzzy */
!
