That seems like a change worthy of doing regardless, so +1 on trying this.  We
can't use %m in frontend though can we?  Isn't using strerror_r() like in the
attached what we need to do?  If so I can go ahead and do that, and it
shouldn't make the buildfarm any worse off than it is, and ideally we'll get
clues as to why msys is happy to copy the files with Perl but not read them
from C.
