From 63e8aea74e992bd8667e35a0e646110acc1f0d7c Mon Sep 17 00:00:00 2001 From: Brandon Casey Date: Thu, 28 Aug 2008 17:47:22 -0500 Subject: [PATCH] dir.c: Avoid c99 array initialization The following syntax: char foo[] = { [0] = 1, [7] = 2, [15] = 3 }; is a c99 construct which some compilers do not support even though they support other c99 constructs. This construct can be avoided by folding these 'special' test cases into the sane_ctype array and making use of the related infrastructure.
