Subject: [Qemu-devel] [PATCH] linux-user F_DUPFD_CLOEXEC fix
Date: Wed, 9 Sep 2009 12:06:11 -0400 (EDT)	[thread overview]
Message-ID: <20090909120328.R4195@stanley.csl.cornell.edu> (raw)

Hello

on older machines, the F_DUPFD_CLOEXEC define is not available.  So 
linux-user targets fail to compile.

This fix simply disables the feature if it's not available.

Vince
