[PATCH ld/maint-diff-quiet-w] Windows: redirect fopen("/dev/null") to fopen("nul")

From: Johannes Sixt <j.sixt@viscovery.net>
Date: Feb 25, 2010, 08:49 UTC
Message-ID: <4B86399E.3090508@viscovery.net>

From: Johannes Sixt <j6t@kdbg.org>

An instance of fopen("/dev/null",...) was added to the code base. On Windows, we have to use "nul" instead. This implements a compatibility wrapper of fopen() that checks for this particular condition.
