With input such as
%token<fl> yVL_CLOCK "/*verilator sc_clock*/"
we generate
yVL_CLOCK = 610, /* "/*verilator sc_clock*/" */
which is invalid since the comment will actually be closed on the
first "*/". Let's turn "*/" into "*\/" to avoid this. But GCC will
also warn about "/*" inside a comment, so let's "escape" it too.
