Subject: Problems compiling GhostScript with DJGPP

Hello,

	I am trying to compile GhostScript 2.4.1 with GCC. Everything has
gone OK so far with just printer devices and I can now print out files that
used to make my machine fall over with memory errors.

	Now, I want to add the VGA device so that I can preview the files
before printing and this is where the problems start.  The device driver
assumes that I can write directly to the screen memory and when I run the
program I get a segmentation fault as soon as it attempts a screen write. 

	How can I make go32 allow me to write to a certain area of memory? I
don't want to re-write large chunks of code to use higher level graphics
primitives so what should I do? Has anyone else managed to compiler
GhostScript under DJGPP?

Thanks for any help,

Paul.
