Added some MFC documentation (with the help of Francois Gouget).

+        options for the MFC and the ATL part (to get the include paths

+        Then when compiling it you will indeed need a number of
+        <literal>_AFX_NO_XXX</literal> macros. But this is not enough
+        and there are other things you will need to
+        '<literal>#ifdef</literal>-out'.  For instance Wine's richedit
+        support is not very good.  Here are the AFX options I use:
+      </para>
+      <para>
+        <programlisting>
+#define _AFX_PORTABLE
+#define _FORCENAMELESSUNION
+#define _AFX_NO_DAO_SUPPORT
+#define _AFX_NO_DHTML_SUPPORT
+#define _AFX_NO_OLEDB_SUPPORT
+#define _AFX_NO_RICHEDIT_SUPPORT
+        </programlisting>
+      </para>
+      <para>
+        You will also need custom ones for
+        <function>CMonikerFile</function>, <function>OleDB</function>,
+        <function>HtmlView</function>, ...
+      </para>
+      <para>
+        We recommend using Wine's msvcrt headers (<literal>-isystem
+        $(WINE_INCLUDE_ROOT)/msvcrt</literal>), though it means you
+        will have to temporarily disable winsock support
+        (<literal>#ifdef</literal> it out in
+        <filename>windows.h</filename>).

+        You should use g++ compiler more recent than g++ 2.95. g++
+        2.95 does not support unnamed structs while the more recent
+        ones do, and this helps a lot. Here are the options worth
+        mentioning:
+        <itemizedlist>

+            <para>
+              <literal>-fms-extensions</literal> (helps get more code

+      </para>
+      <para>
+        When you first reach the link stage you will get a lot of
+        undefined symbol errors. To fix these you will need to go back
+        to the source and <literal>#ifdef</literal>-out more code
+        until you reach a 'closure'. There are also some files that
+        don't need to be compiled.
+      </para>

+        Maybe we will have ready-made makefile here someday...
