Bug#740286: gnat-4.9: s-osinte-posix.adb is wrong about timespec.tv_nsec compared to gnat-4.8

[Ludovic Brenta <ludovic@ludovic-brenta.org>]

The reasons for the upstream change are explained in the bug report I
referenced: http://gcc.gnu.org/PR54040, and discussed in detail in
the thread referenced there, viz.:

http://gcc.gnu.org/ml/gcc-patches/2013-11/msg01504.html

Since the decision to use time_t instead of long has been discussed
and approved upstream, I think you should take your objections there,
i.e. by following up to that thread.

I will not change s-osinte-posix.adb without approval from upstream
but I will take your suggestion to change ada-kfreebsd.diff to use
s-osinte-posix.adb, introducing time_t in the private part of
s-osinte-kfreebsd-gnu.ads.
