From f4fec336071552525735f0c95b7eb7c5e88801de Mon Sep 17 00:00:00 2001 From: =?utf8?q?P=C3=A1draig=20Brady?= Date: Fri, 22 Dec 2017 12:33:30 +0000 Subject: [PATCH] doc: describe recent build checks for 32 bit time_t * README: Document the new handling of 32 bit time_t, with examples of how to build in 64 bit mode on AIX. Also mention that GNU make is desired on AIX due to its mishandling of the "[" target.
