From daf767b16aeb32e5b9a77066ba130fe723f875ca Mon Sep 17 00:00:00 2001 From: Stefan Weil Date: Sat, 3 Dec 2011 22:32:37 +0100 Subject: [PATCH] w32: Disable buffering for log file W32 does not support line buffering, but it supports unbuffered output. Unbuffered output is better for writing to qemu.log than fully buffered output because it also shows the latest log messages when an application crash occurs.
