from 4.2.29 4.2.31 is the last known GPL2 version changes for 4.4: - pulled upstream patch to fix bug #27017, #28824 and #28872 - using a workaround to address bug #27299, this was fixed in development branch 4.5.3 by using a new version of gnulib. however, upgrading gnulib needs too much effort here. changes for 4.2: - 4.2.31's gnulib/m4/extension.m4 won't work with autoconf 2.65, fix it by removing gnulib's AC_USE_SYSTEM_EXTENSIONS Signed-off-by: Qing He <qing.he@intel.com>
