<p>Comment (by Roland Haas):</p>
<p>@{1648a2da-81db-4efd-8c01-a5e594c71763} and I had a some offline discussion and iterated over the best regular expression to use. In he course of this we realised that <code>$(...)</code> cannot be used b/c there is already an option list that relies on <code>$(…)</code> being expanded as only a make variable to set <code>C_MAKE_DEPENDS</code> using <code>CC</code> which is only known to <code>make</code> but not in the environment (usually).</p>
