From cba22528fa897728ebbffb95c05037ec9a20ea7c Mon Sep 17 00:00:00 2001 From: Brandon Casey Date: Fri, 8 Feb 2008 20:32:47 -0600 Subject: Add compat/fopen.c which returns NULL on attempt to open directory Some systems do not fail as expected when fread et al. are called on a directory stream. Replace fopen on such systems which will fail when the supplied path is a directory.
