--- Comment #57 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Eric Botcazou <ebotca...@gcc.gnu.org>: https://gcc.gnu.org/g:41974d6ed349507ca1532629851b7b5d74f44abc commit r16-2688-g41974d6ed349507ca1532629851b7b5d74f44abc Author: Nicolas Boulenguez <nico...@debian.org> Date: Fri Jul 25 15:02:06 2025 +0200 Ada: Add System.C_Time and GNAT.C_Time units to libgnat The first unit provides the time_t, timeval and timespec types corresponding to the C types defined by the OS, as well as various conversion functions. The second unit is a mere renaming of the first under the GNAT hierarchy. This removes C time types and conversions under System, and from bodies and private parts under GNAT, while keeping visible types and conversions under GNAT as Obsolescent.
