I don't see the reason for upstream to change tv_nsec to time_t at all
in s-osinte-posix.adb., see the POSIX spec and Linux/etc header files
referred to earlier! Independent on if it is a private or not.
s-osinte-linux-ads:
type time_t is private;
type time_t is new System.Linux.time_t;
type timespec is record
tv_sec : time_t;
tv_nsec : time_t;
end record;
pragma Convention (C, timespec);
s-osinte-kfreebsd-gnu.ads:
type time_t is new long;
type timespec is record
tv_sec : time_t;
tv_nsec : time_t;
end record;
pragma Convention (C, timespec);
(same problems with kFreeBSD as for Hurd. Therefore s-osinte-posix.adb
was modified to s-osinte-kfreebsd-gnu.adb in ada-kfreebsd.diff (this
part of the patch is not necessary, it should be possible to use the
posix (.adb) version))
