Subject: [Qemu-devel] [PATCH for-2.5] w32: Use gcc option -mthreads
Date: Thu, 26 Nov 2015 12:19:56 +0100	[thread overview]
Message-ID: <1448536796-9299-1-git-send-email-sw@weilnetz.de> (raw)

QEMU uses threads / coroutines, therefore support for thread local storage
and thread safe libraries (-D_MT) must be enabled by using -mthreads.
