(See bug 11497, which is quite similar to this)
An input file containing:
<![CDATA[if (a > 0) val >>= a;]]>
when processed using db2ps, produces a special character for '>>', rather
than two greater-than signs next to each other, which is the intent.
The HTML output, produced using db2html, seems fine.
