Subject: Declare asctime_r, ctime_r, gmtime_r, localtime_r for C2X
Date: Fri, 8 Nov 2019 20:49:28 +0000 [thread overview]
Message-ID: <alpine.DEB.2.21.1911082048450.17641@digraph.polyomino.org.uk> (raw)
C2X adds the asctime_r, ctime_r, gmtime_r and localtime_r functions.
This patch duly adds __GLIBC_USE (ISOC2X) to the conditions under
which <time.h> declares them.
Tested for x86_64.
