In fact, access to the gnulib repository through CVS has been disabled,
or more precisely, got broken and was never restored; see:
<http://lists.gnu.org/archive/html/bug-gnulib/2013-05/msg00008.html>
Note that support for CVS is not removed completely and unthinkingly
by this change: only support for CVS checkouts of gnulib itself is
removed. For example, the 'bootstrap' script still cater to .cvsingore
files and CVS directories, for the benefit of those poor gnulib clients
still stuck with CVS. Ditto for the 'gnulib-tool' script itself.

I needed gcc's clz to determine the most significant bit of a

count-one-bits module.

These three scripts are too closely tied to automake internals to
be independently useful. In fact, automake would rather that
people did not mix the latest version of these scripts with older
versions of automake, as there is no effort being put into
maintaining backwards-compatibility when these scripts are updated.
The remaining scripts pulled from automake, such as mdate-sh or
depcomp, are independently useful, so a future patch may end up
reparenting those scripts to have gnulib instead of automake as
the master owner.

For now, this replacement focuses solely on compilation
compatibility, and assumes that isatty() and ttyname_r() work

At least libvirt would like to use the lighter-weight fdatasync
on platforms where it is supported, while still guaranteeing full
sync (via the heavy-weight fsync fallback) on all platforms.
I've got an open question to the Austin Group, since the POSIX 2008
wording is self-contradictory (unlike fsync, fdatasync requires
EBADF on non-writable fds, but still mentions that read() errors
must be propagated). I can see how fsync() would affect atime after
read() while fdatasync() can skip that, explaining why fdatasync()
might have the EBADF requirement, but on the other hand, that prevents
an implementation (like ours) where fdatasync is a straight alias of
fsync. At any rate, glibc allows fdatasync on read-only fds.
