Unfortunately I have very few interests for Alpha, I only worked on it
because it was one of the Debian supported architecture.

alpha had no fdatasync syscall before 2.6.22 (kernel development on
alpha is mostly dead, so it is lacking behind other architectures).
This patch therefore tries to call the fdatasync syscall and if it
doesn't exist, it call the fsync one. On architectures that are known
to have a fdatasync syscall, only fdatasync is called.
Note that the patch in bugzilla has a minor issue that causes the
testsuite to fail on arm with this patch, you should use this version
instead:

You probably want this patch:

It's probably the best way (I have been successful once using this
method), but it's not easy either. The glibc maintainers are reluctant
to do that if there is no official alpha porter.
