[Nasm-devel] Compilation fails on master branch

[KO Myung-Hun]

Hi/2.

I've tried to compile on master branch. However, it failed due to
`ATTRIBUTE', which seems to be a macro, like:

-----

If I define `ATTRIBUTE(x)=__attribute__((x))', all the problems go away.

I'm using gcc v12.3.0.

What's the problem ?
