Yes, the new file .gitattributes has recently been committed by me
as part of an upgrade.

I do assume that the files affected are only for the Windows build
that has been added in version 4.0.0.

I do not know how to fix this problem (and whether this is just a
nuisance or an actual problem).

The upstream repository is https://git.yzena.com/gavin/bc and I have
performed a "diff -r" of the distfile of the math/gh-bc port against
the files in vendor/bc in our repository (before the commit to that
repository) and thus any change that we locally apply will need to
be upstreamed.
