What came to my mind here was dev86's bcc. I didn't even believe gcc compiles Intel 8086 code, though I've heard that it's used to compile Bochs BIOS, so... Anyways, I've not tried to get it to build with bcc, though I saw a mailing list post (I can't find it now) about it, that remained unanswered. > 2. Next is the assembler bits.
