Subject: [gentoo-dev] [PATCH] profiles/default/linux: set gl_cv_type_time_t_bits_macro=no
Date: Fri, 17 Dec 2021 09:41:35 -0500 [thread overview]
Message-ID: <20211217144135.20907-1-floppym@gentoo.org> (raw)
This is intended to prevent packages from automatically switching to
64-bit time_t on 32-bit ABIs. Making this switch in an uncontrolled
manner will lead to inconsistent library ABIs that fail at runtime.
At a later time, we will introduce new profiles to enable 64-bit time_t
distro-wide.
