I am trying to make sense of the contents of the QEMU LICENSE file which states 
this:

    "1) QEMU as a whole is released under the GNU General Public License,
    version 2."

but then later states this:

    "As of July 2013, contributions under version 2 of the GNU General Public
    License (and no later version) are only accepted for the following files
    or directories: bsd-user/, linux-user/, hw/misc/vfio.c, hw/xen/xen_pt*."

I am working on getting libdecnumber source with GPLv2 licensing, but the 
previous
paragraph suggests that it will not be accepted either.
