-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.
