    A) You need LFN support.

-2. Dynamic modules
+   Q) Libraries built OK, but linker complains about `vsnprintf' every time I
+      compile some demo.
+   A) Upgrade to DJGPP 2.04.
+   A) Add `vsnprintf.c' to the CORE_SOURCES in `src/Makefile.DJ' (untested!).
+   A) The following hack should be safe in 90% of the cases, but if anything
+      goes wrong, don't come back to me crying. Anyway, patch `src/imports.c'
+      with the following line:
+	#define vsnprintf(buf, max, fmt, arg) vsprintf(buf, fmt, arg)
 
-   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) `make' complains about DXE3 or something, yet it builds the libraries.
+   A) DXE3 refers to the DJGPP dynamic modules. You'll need either the latest
+      DJGPP distro, or download the separate package from my web page. Read the
+      DXE3 documentation on how to use them. Hint: build your export object
+      file; then link it with your application. For example:
+	dxe3res -o dxe3tbl.c gl.dxe glu.dxe glut.dxe
+	gcc -o dxe3tbl.o -c dxe3tbl.c
+	gcc -o OUT.exe dxe3tbl.o IN.c -liglut -liglu -ligl -ldl
 
-   Q) I have DXE2, but I couldn't build the `dxe2gen.exe'.
-   Q) I built `dxe2gen.exe', but it doesn't do the job right.
-   A) There is a patched version on my web page.
+2. Using Mesa for DJGPP
 
-   Q) DXE2 modules give me headaches...
-   A) The DXE2 modules are not compulsory. The static libraries are still built
-      and you can use them in the old-fashioned, classic way... and learn to
-      live with your ~2MB executable size. For example:
-	gcc -o OUT.exe IN.c -lglut -lglu -lgl
+   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
+      Glide port is on my web page). If you have a Matrox Millennium I card,
+      you just MIGHT be lucky... If you haven't, sorry; everything is done in
+      software. Suggestions?
 
-   Q) Okay, DXE2 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
-	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) I tried to set refresh rate w/ DMesa, but without success.
+   A) Refresh rate control works only for VESA 3.0. If you were compiling for
+      Glide, see Glide info. If not, sorry!
 
    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.
-   A) Another weird "feature" is that buffer width must be multiple of 4 (I'm a

+   A) Another weird "feature" is that buffer width must be multiple of 8 (I'm a
       lazy programmer and I found that the easiest way to keep buffer handling
       at peak performance ;-).

+   Q) My demo doesn't display text. I know I used the GLUT font routines!
    A) Then you probably use GLUT as a DXE. Well, there is no direct access to
       variables due to the way DXE works. Read the documentation. The author of
       GLUT took this into account for _WIN32 DLL's only; I don't want to modify
       his headers. The only workaround is to link GLUT the old way :-(
 
-   Q) DMesa is so SLOOOW! The Win32 OpenGL performs so much
-      better...

-   Q) I have a super/mega/ultra monitor and all you can do is 60Hz? My eyes are

+
+
+
+Introduction
+------------
+
+Mesa uses an even/odd version number scheme like the Linux kernel.
+Even-numbered versions (such as 5.0.x) designate stable releases.
+Odd-numbered versions (such as 4.1.x) designate new developmental releases.
+
+Mesa 5.0.1 just fixes bugs found since the 5.0 release.  See the VERSIONS
+file for details.
+
+
+Device Driver Status
+--------------------
+
+A number of Mesa's software drivers haven't been actively maintained for
+some time.  We rely on volunteers to maintain many of these drivers.
+Here's the current status of all included drivers:
+
+
+Driver			Status
+----------------------	---------------------
+XMesa (Xlib)		implements OpenGL 1.4
+OSMesa (off-screen)	implements OpenGL 1.4
+FX (3dfx Voodoo1/2)	implements OpenGL 1.3
+SVGA			implements OpenGL 1.3
+Wind River UGL		implements OpenGL 1.3
+Windows/Win32		implements OpenGL 1.4
+DJGPP			implements OpenGL 1.4
+GGI			implements OpenGL 1.3
+BeOS			implements OpenGL 1.4
+Allegro			needs updating
+D3D			needs updating
+
+Note: supporting OpenGL 1.4 (vs. 1.3 or 1.2) usually only requires that the
+driver call the _mesa_enable_1_4_extensions() function.

-** 2. The GL API dispatch table is a fixed size (with plenty of extra slots).

- * DESCRIPTION
- *
- * This file contains a straightforward implementation of a fixed-sized
- * hash table using self-organizing linked lists [Knuth73, pp. 398-399] for
- * collision resolution.  There are two potentially interesting things
- * about this implementation:
- *
- * 1) The table is power-of-two sized.  Prime sized tables are more
- * traditional, but do not have a significant advantage over power-of-two
- * sized table, especially when double hashing is not used for collision
- * resolution.
- *
- * 2) The hash computation uses a table of random integers [Hanson97,
- * pp. 39-41].
- *
- * FUTURE ENHANCEMENTS
- *
- * With a table size of 512, the current implementation is sufficient for a
- * few hundred keys.  Since this is well above the expected size of the
- * tables for which this implementation was designed, the implementation of
- * dynamic hash tables was postponed until the need arises.  A common (and
- * naive) approach to dynamic hash table implementation simply creates a
- * new hash table when necessary, rehashes all the data into the new table,
- * and destroys the old table.  The approach in [Larson88] is superior in
- * two ways: 1) only a portion of the table is expanded when needed,
- * distributing the expansion cost over several insertions, and 2) portions
- * of the table can be locked, enabling a scalable thread-safe
- * implementation.

- * DESCRIPTION
- *
- * This file contains a simple, straightforward implementation of the Park
- * & Miller "Minimal Standard" PRNG [PM88, PMS93], which is a Lehmer
- * multiplicative linear congruential generator (MLCG) with a period of
- * 2^31-1.
- *
- * This implementation is intended to provide a reliable, portable PRNG
- * that is suitable for testing a hash table implementation and for
- * implementing skip lists.
- *
- * FUTURE ENHANCEMENTS
- *
- * If initial seeds are not selected randomly, two instances of the PRNG
- * can be correlated.  [Knuth81, pp. 32-33] describes a shuffling technique
- * that can eliminate this problem.
- *
- * If PRNGs are used for simulation, the period of the current
- * implementation may be too short.  [LE88] discusses methods of combining
- * MLCGs to produce much longer periods, and suggests some alternative
- * values for A and M.  [LE90 and Sch92] also provide information on
- * long-period PRNGs.
