[Nicolas Boulenguez <nicolas@debian.org>]

Package: gnat-4.9
Followup-For: Bug #182360
Control: retitle -1 [Fixed in 5.2] GNAT.OS_Lib.Close ignores return value

Adacore has found a way to preserve compatibility *and* allow the user
to raise an exception.
>From s-os_lib.ads:
   procedure Close (FD : File_Descriptor; Status : out Boolean);
   --  Close file referenced by FD. Status is False if the underlying service
   --  failed. Reasons for failure include: disk full, disk quotas exceeded
   --  and invalid file descriptor (the file may have been closed twice).

   procedure Close (FD : File_Descriptor);
   --  Close file referenced by FD. This form is used when the caller wants to
   --  ignore any possible error (see above for error cases).
