From eb120e699f3faea2d71cd9cb79a8cf4f79ec1d45 Mon Sep 17 00:00:00 2001 From: Brandon Casey Date: Wed, 7 May 2008 12:34:18 -0500 Subject: compat/fopen.c: avoid clobbering the system defined fopen macro Some systems define fopen as a macro based on compiler settings. The previous technique for reverting to the system fopen function by merely undefining fopen is inadequate in this case. Instead, avoid defining fopen entirely when compiling this source file.
