[MapServer C Library] Include parsing not closing Symbols (?)

[jmckenna@…]

Assefa discovered an interesting one (bare with me as I try to explain it, as I
bet at first you'll think it is a mapscript issue I'm sure):

- in PHP/Mapscript, a loop that simply creates a map object, with a mapfile that
has an include, AND has a symbol file, fails
- the odd thing is that if you add an extra END in the symbol file it does not
fail anymore (?)

Here is a tiny test case (http://www2.dmsolutions.ca/netbin/include-bug.zip) 1KB
  - run test.php

(i'm not sure if this is related to bug#2013 - font handling with includes)

PHP Script
==========

<?php
if (!extension_loaded("MapScript")) 
     dl("php_mapscript.dll");

for ($i=0; $i<4; $i++)
{
  $oSourceMap = ms_newmapobj('./test.map');
  if ($oSourceMap)
    echo "success <br>\n";
  else
    echo "failure <br>\n";
}
?>

Mapfile
=======

NAME include-test
STATUS ON
SIZE 400 300
SYMBOLSET ./symbols.sym
EXTENT -180 -90 180 90
UNITS DD
IMAGECOLOR 255 255 255

  IMAGEPATH "/ms4w/tmp/ms_tmp/" 
  IMAGEURL "/ms_tmp/"
END

INCLUDE "./include.lay"

END # Map File

Include File
