some licence or something. Especially the C compiler, what is its status?
I am interested in implementing Minix on a 68000 or 020. Is the C
compiler adaptable or is there another one available?
Are the upper levels of Minix general enough so that I would just
have to replace the assembly and very low level stuff? I also want
to add paging or proper segmentation (since I'm not using a brain-dead
processor).
Thanks for any info.

The GNU optimizing 'C' compiler beta test version is available via ftp or uucp from osu-eddie. Send mail if you want the instructions file. I have been porting the compiler to a 16-bit processor similar to pdp-11. It is better quality than any commercial compiler we have been able to obtain. Machine descriptions for 68000,68020,vax are available with it! There are many assumptions of large address space (cpp, for instance, reads included files with one read into a huge buffer) that need attention for it to work on a 16-bit. These are not design flaws, they are more efficient for 32-bit machines, and there was no intention of supporting smaller address spaces. Semantic, optimizing, and code generation passes are one program. They need to be split into three programs for a 16-bit machine. -- Stuart D. Gathman <..!seismo!dgis!bms-at!stuart>
