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.

I thought they already use nasm for their builds. At least their wiki
says so [1].
