Subject: Declare timegm for ISO C2X
Date: Wed, 1 Jun 2022 23:08:47 +0000 [thread overview]
Message-ID: <alpine.DEB.2.22.394.2206012307340.3755786@digraph.polyomino.org.uk> (raw)
The next revision of the ISO C standard has added the timegm function
(that was already supported in glibc). Update the feature test
conditionals on its declaration in <time.h> accordingly.
Tested for x86_64.
