+From 03cca78d24d716eec792f86f5b0bc69886fad981 Mon Sep 17 00:00:00 2001

+Subject: [PATCH] configure.ac: fix compatibility with autoconf 2.70
+
+With autoconf 2.70, not quoting the second argument to one of the AS_IF
+macro expansions leads to generation of invalid shell code affecting the
+first nested ERROR_IF_NO_PROG expansion.
+
+The invalid shell code leads to an error resembling:
+
+  ./configure: line 18826: syntax error near unexpected token `newline'
+  ./configure: line 18826: `    '''
+
+Fix the issue by quoting the second argument to the affected AS_IF,
+similar to the quoting found elsewhere in configure.ac.
