 2. Dynamic modules
 
    Q) What are you mumbling about dynamic modules?
-   A) You must have the DXE2 package (available on SimTel.Net, courtesy of
-      Andrew Zabolotny) installed in order to build the dynamic modules.
-
-   Q) I have DXE2, but I couldn't build the `dxe2gen.exe'.

+   A) The DXE3 modules are not compulsory. The static libraries are still built

+   Q) Okay, DXE3 modules are built. How can I use them?
    A) Build your export object file; then link it with your application.
       For example:
-	dxe2res -o dmesadxe.c gl.dxe glu.dxe glut.dxe
-	gcc -o dmesadxe.o dmesadxe.c
+	dxe3res -o dmesadxe.c gl.dxe glu.dxe glut.dxe
+	gcc -o dmesadxe.o -c -fno-builtin dmesadxe.c
 	gcc -o OUT.exe dmesadxe.o IN.c -liglut -liglu -ligl -ldl
 
-   Q) What is that `dxe2res.exe' thing?
-   A) That is an utility that generates the export file for a given set of
-      modules. If you can't find it in the DXE2 package, you must be looking at
-      the wrong archive :)

 3. Using Mesa for DJGPP
 
-   Q) Does this build work in Win9x?
-   A) Yes.
-
-   Q) Does it work under NT (W2k, XP) core?
-   A) Uh... probably not!
+   Q) DMesa is so SLOOOW! The Win32 OpenGL performs so much better...
+   A) Is that a question? If you have a Voodoo3/Banshee card, you're lucky. The

    Q) I made a simple application and it does nothing. It exits right away. Not
       even a blank screen.
-   A) The current version supports only RGB[A] modes, for it made no sense to
-      me to endorse color-index (aka palette) modes.
    A) Single-buffered is not allowed at all. Until I can find a way to use
       *REAL* hardware acceleration, it won't get implemented.
