Yes.  Also, GNU applications like Make and Coreutils currently check
for "st_mtim.tv_nsec" when configuring support for nanosecond
resolution, so it will make it a bit easier on the GNU app developers
if glibc uses the name "st_mtim" as well.

The BSD name "st_mtimespec" is news to me.  I guess GNU apps will have
to learn about it at some point.
