I don't know if this is compatible with the GPLv2.  The requirement to
include the README file may be considered an additional restriction.

This is not compatible with the GPLv2.  It is an additional restriction.
I don't believe this is a problem with the GPLv3, but if you use it
under the GPLv3 then you cannot link it with GPLv2 applications.
