DOS ain't dead

https://codeberg.org/tkchia/gcc-iamcu

This is a GCC toolchain which produces code for the (partly deprecated) x86-32 IAMCU ABI. The ABI uses registers to pass parameters to functions, and was apparently intended for use with embedded devices running on Intel Quark processors -- though I think it can be repurposed to target other x86-32 systems (e.g. Linux, or MS-DOS on 80386).

There are currently just the GCC compiler, libgcc, and Binutils, without any C library runtime.
