From 94c8ff3a01d9bd1005f066a0ee3fe43c842a43b7 Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Tue, 15 Jan 2013 14:23:37 +0100 Subject: w32: Make qemu_vfree() accept NULL like the POSIX implementation On POSIX, qemu_vfree() accepts NULL, because it's merely wrapper around free(). As far as I can tell, the Windows implementation doesn't. Breeds bugs that bite only under Windows. Make the Windows implementation behave like the POSIX implementation.
