From 590e081dea7c064056941bfae28b25ce956585f5 Mon Sep 17 00:00:00 2001 From: Rafael Gieschke Date: Thu, 19 May 2011 13:37:55 +0200 Subject: [PATCH] ident: add NO_GECOS_IN_PWENT for systems without pw_gecos in struct passwd Allow NO_GECOS_IN_PWENT to be defined in the Makefile for platforms that lack the pw_gecos field in their "struct passwd", in which case the uppercased user name is used instead via the standard '&' replacement mechanism.
