From dc60870eb02edb6b0163a77cc9ca523d692bc385 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Bj=C3=B6rn-Egil=20Dahlberg?= Date: Tue, 15 Jan 2013 17:32:19 +0100 Subject: Fix LM_TRY_ENABLE_CFLAG to use correct environment LM_TRY_ENABLE_CFLAG takes which environment variable should be updated but only CFLAGS was updated.
