[Qemu-devel] [PATCH 05/11] linux-user: fix mq_* compilation problems

From: riku . voipio
Subject: [Qemu-devel] [PATCH 05/11] linux-user: fix mq_* compilation problems
Date: Thu, 13 Aug 2009 23:06:18 +0300

From: Nathan Froyd <address@hidden>

mqueue.h is only available if __NR_mq_open is defined.  So don't include
it unconditionally.  Similarly, the mq_* family of syscalls depend on
__NR_mq_open.  Finally, the copy_{from,to}_user_mq_attr functions should
not be defined unconditionally, but only if we're going to use the mq_*
