Lack of termios.h to port some package to a-shell

Hi,

I'm now trying to port MicroEmacs to a-shell environment which seems much easier than porting GNUEmacs.
As a first step, as a practice, I'm trying to compile kilo a simple text editor (https://github.com/antirez/kilo) using WASI-SDK.
Then, I noticed that WASI-SDK does not provide termios.h features on which both kilo and MicroEmacs are based.

Can you give me any advice on how I can work around such an issue?

Moreover, as I tried to clone holzschu's version of WASI-SDK, I found that src/llvm-project @ bb31aec is not available at this moment and hence I cannot properly fetch the full package of the tailored version of the SDK. Currently, I'm using the original version of it instead to compile the above packages.

Sincerely,
MS
