Yes but not exactly GCC but [DJGPP](http://www.delorie.com/djgpp/) that is a GCC for MsDOS and is 32bit only. It uses CWSDPMI instead of the DOS/4GW extender.

Someone managed to build the original Doom using DJGPP: https://virtuallyfun.com/wordpress/2017/07/29/null-doom-gcc-1-39-go32-dpmi/

I was thinking about another solution: Use GCC to generate assembly language from the .c files or at least some critical c routines. link them all with Watcom. Someone was...

Actually when reading OpenWatcom changelog it seems they support COFF so it means that DJGPP object files could be linked with Watcom? I probably misunderstood something, it seems too nice...

I build FastDoom using Open Watcom 2.0 and there is no speed differences compared to version 1.9 Is there any reason you use only one pass for tasm in your...

I think you could then compile the asm with tasm and then convert the OMF32 generated .obj files in COFF32 .o files using objconv. (I had to build objconv for...

I think Boom used Allegro. https://liballeg.org/old.html For you only the sound library would be useful for you. Allegro can be compiled with both Watcom and djgpp. Latest DOS version seems...

I agree, this would be nice, I am used to play with vertical mouse movement and I think it would be even better to have a key to toggle vertical...

I will try again with 1850. I was also thinking to make the average color but it would be time consuming. the ideal solution would be to precalculate a mapping...

Would be nice indeed, Unfortunately it would require a lot of work because in_opus is based on the libopusfile library that can only handle ogg container. For now when I...
