Isn't that what you'd want when building for Windows?

On Windows that would be the mingw-w64 generator and it's expecting files with only \n (otherwise it makes huge diffs).
I'm not sure if there are other cases where widl would be used to produce Windows based headers.

There are more places that would need to be fixed for consistency. Maybe we could use _set_fmode(_O_BINARY) in main() instead?

Is this a MS-only thing ? I don't mind having this patch only in mingw-w64-tools (which also have some extra patch as well).
In general it may not be the proper way to handle this. For writing all files widl generates, it should be fine. But for reading files the "binary" mode is not currently used and it may break reading files that used to be read properly on Windows ?

Yes, it would need an #ifdef.

Which files do you mean? The only non-binary files that widl generates are headers and C files.
Generally speaking, widl output is cross platform, so it should generate the same output on regardless of host platform used. Windows line ending breaks that.

OK for me.

I meant that for generated files it's fine, so I agree with you. I fear that forcing binary mode for input files as well may break reading some files with windows line ending on Windows. I don't think that's the case in mingw-w64 but it may have some side effects elsewhere.

That's a good incentive to fix this.

Note that binary mode results in more or less what we use on Unix, so if reading in text or binary mode changes output, it would most likely mean that we don't do it right on one of hosts. In practice, new lines are consumed by lexer and both modes should be fine.

You could use something like
if (type_iface_get_async_iface(iface) == iface)
to avoid extra as_async argument.
