+Subject: [PATCH] aconfigure.ac:  Fix autoconf issue with opencore-amrnb on
+ older systems
+
+autoconf 2.63 on CentOS6 produces a bad ./aconfigure file related to
+opencore-amrnb.
+
+./aconfigure: line 15158: syntax error near unexpected token `fi'
+
+To get around this, a 'true;' needed to be added to the Ok case of
+AC_ARG_WITH(opencore-amrnb)
