Yea this b) is generally what is recommended see also
https://gcc.gnu.org/ml/gcc-patches/2016-06/msg01358.html which reminds me that
the -fno-ident thing is still not upstream.
Or maybe we should have a -fno-file which suppresses .file like I proposed for
.ident. At least this would fix it once and for all.
