From bfa8fccf477ed2567b035f1c6a3cb2b74ec4ef67 Mon Sep 17 00:00:00 2001 From: Jakub Narebski Date: Fri, 18 Jan 2008 02:03:51 +0100 Subject: [PATCH] autoconf: Add checking for unsetenv function Update configure.ac (and config.mak.in) by adding test for unsetenv (NO_UNSETENV). Add comment about NO_UNSETENV to Makefile header, as original commit 731043fd adding compat/unsetenv.c didn't do that.
