A) You need LFN support.
A) When compiling for Glide (FX=1), pay attention to Glide path.
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) I made a simple application and it does nothing. It exits right away. Not
even a blank screen.
A) Only DMesa+FX supports single-buffered. The standard VESA/VGA drivers
will always work in double-buffered modes. If/When I will find a way to
use *REAL* hardware acceleration for a specific card, it might or might
not support single-buffered modes.
A) The pure software drivers (VESA/VGA) support only double-buffered modes.
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!
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

* Triangle Rasterizer Template
*
* This file is #include'd to generate custom triangle rasterizers.
*
* The following macros may be defined to indicate what auxillary information
* must be interplated across the triangle:
* INTERP_Z - if defined, interpolate Z values
* INTERP_RGB - if defined, interpolate RGB values
*
* TAG - function name
* CULL - enable culling for: 0=no, 1=back, -1=front
*
* SETUP_CODE - to be executed once per triangle (usually HW init)
*
* For flatshaded primitives, the provoking vertex is the final one.
* This code was designed for the origin to be in the upper-left corner.
*
* Inspired by triangle rasterizer code written by Brian Paul.
