It seems to have been fully removed in this changeset [1] without even
leaving an option to install it.

Following some of the problem reports, they do consider it a bug that
it was being installed. Maybe the mingw.org team relied on the old
behaviour and considered that they didn't need to include it with the
runtime?

The version in gcc seems to be the most recent, which makes sense
given it's a subproject.

To maintain the status quo, we could build it after gcc (see
attached), otherwise contacting the mingw.org project is probably the
best option.

Nikos,

Do you have the time to ask the mingw.org project their thoughts on
this issue? If they consider it part of gcc, then we can build it,
otherwise they can include it in mingwrt.

Thanks,

Tony
