    A) You need LFN support.

+   A) Add `vsnprintf.c' to the CORE_SOURCES in `src/Makefile.DJ' (untested!).

    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

+   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 ;-).

    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
