Yet another 16-bit fix for BGI and GRX. GrColor is not used in libbcc.h because including the grx headers is not and should not be a requirement for using GRX's BGI and the GrColor type may be unavailable. Compiled and tested with BCC / DOS only. What if I try to port GRX to BCC / WIN32 after -pre4?

Well if you want, why not. But if you have the time it will be better work in the "official" (mingw) version, there are big problems with te win32 driver, see http://www.gnu.de/software/GRX/problems.html (some of them are resolved more or less in 2.4.5).
If you like I can send simple instructions to install and go with mingw.

I'd appreciate to get these instructions too. Many thanks for all your work.

Hi Waldemar (and thanks).
Chances are you know now better than I, how to install Mingw, but here are the instructions. Note I use an old version, but I prefer it because is an all-in-one package and probably the most used version.
------------------
These is a how-to for people who want to make the GRX win32 version, but don't know about the mingw compiler:
1.- First, download the mingw distribution:
ftp://ftp.xraylith.wisc.edu/pub/khan/gnu-win32/mingw32/gcc-2.95.2/ gcc-2.95.2-msvcrt.exe
ftp://ftp.xraylith.wisc.edu/pub/khan/gnu-win32/mingw32/gcc-2.95.2/ mingw32-docs-html.exe
ftp://ftp.xraylith.wisc.edu/pub/khan/gnu-win32/mingw32/gcc-2.95.2/fixes/ quote-fix-msvcrt.exe
2.- Create a \MINGW dir and decompress the three files on it (The files are not instalers, only auto-decompress files)
3.- Create a \MINGW\SETVAR.BAT file with the line:
SET PATH=C:\MINGW\BIN;%PATH%
4.- Open a DOS window and execute \MINGW\SETVAR
5.- Go to the dir you have the GRX 2.4.x distribution.
Go to the src subdir and execute "make -f makefile.w32" Go to the test subdir and execute "make -f makefile.w32" Go to the test\bgi subdir and execute "make -f makefile.w32"
Hope this help, M.Alvarez

You know, Win32 is not really on the top of my TODO list, so I'd rather try to write an (s)vga(gl)lib frame driver. Having the GRX programs suid root irritates me a lot.
when I have the time I prefer to work in the framebuffer version (have you checked it?).
No. A lot's to be desired from the NVidia/RIVA framebuffer driver, so I use svgalib.
