I believe it's the *absence* of the PR40134 fix on 4_4-branch that's causing the backport of __sync_synchronize() support to regress. I'm currently testing 4.4-20091215 with relevant bits of PR40134 backported (r151568 + r152975): that cured the build failure, but the testsuite run is not yet finished. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42503
