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.

Commit c6dc8f1 changed test-getcwd-lgpl to allow BSD behavior
where getcwd(NULL,1) allocates the proper size, in addition to
the glibc behavior of allocating exactly one byte then failing
with ERANGE. But the m4 test was still rejecting the former
behavior.
However, merely fixing the test to avoid probing the behavior
would be a regression of commit 8585ce2, since it was the only
reason why rpl_getcwd was being compiled on mingw. Hence, we
have to add a signature check in its place to keep mingw happy.
