From 2bfb8b60809eca003dc3e3fb2697b576c074ec18 Mon Sep 17 00:00:00 2001 From: Yang Tse Date: Fri, 25 Jan 2013 00:44:11 +0100 Subject: zz40-xc-ovr.m4: parentheses balancing of 'case' statements m4 quadrigraph shell comment technique allows proper autoconf parentheses balancing in shell 'case' statements.
