Hi Justin,

Thanks a *LOT* for this fix. The code changes LGTM (can I get
a second Team reviewer please ?).

However, I don't understand the xml documentation patches here.

You have:

 +<samba:parameter name="spoolss_client: os_major"
 +                 context="G"
 +                 type="integer"
 +                 xmlns:samba="http://www.samba.org/samba/DTD/samba-doc">
 +<description>
 +     <para>Windows might require a new os version number. This option allows
 +             to modify the build number. The complete default version number is:
 +             5.0.2195 (Windows 2000). The example is 6.1.7601 (Windows 2008 R2).
 +     </para>
 +</description>
 +<value type="default">2</value>
 +<value type="example">3</value>

 +<samba:parameter name="spoolss_client: os_minor"
 +              context="G"
 +              type="integer"
 +              xmlns:samba="http://www.samba.org/samba/DTD/samba-doc">

 +</description>
 +<value type="default">1381</value>
 +<value type="example">6000</value>

But in the code changes you end up with:

+/* Windows 7 and Windows Server 2008 R2 */
+#define GLOBAL_SPOOLSS_CLIENT_OS_MAJOR_DEFAULT 6
+#define GLOBAL_SPOOLSS_CLIENT_OS_MINOR_DEFAULT 1
+#define GLOBAL_SPOOLSS_CLIENT_OS_BUILD_DEFAULT 7007

Can you fix up the .xml docs to match the code changes
you're making, otherwise it's hard for others to understand
what these parameters mean ?

Thanks.

	Jeremy.
