Also, it's almost always a bad idea to generate code in some language
*directly* from XSLT: you will always have to escape things, and as a
result, XSLT code will not look very readable.  Instead, you may
represent output as a [subset of] target language grammar, like this:

    <stmtseq>
      <stmt>
        <funcall>
          <name>sprintf</name>
          <arglist>
            <arg type="ident">log_str</arg>
            <arg type="string">\n%s: %d: %s: %s</arg>
            <arg type="ident">__FILE__</arg>
            <arg type="ident">__LINE__</arg>
            <arg type="ident">fn</arg>
            <arg type="string">Entering</arg>
          </arglist>
        </funcall>
      </stmt>
      <stmt>
        <funcall>
          <name>log_func</name>
          <void />
        </funcall>
      </stmt>
    </stmtseq>

and allow simple external processor to serialize resulting XML to
actual C code.
