However, this is also a diagnostics issue, that has to be checked with the preprocessed source from the attachment. gcc (GCC) 4.8.0 20130225 on i686-pc-linux-gnu says now: ../../../gcc/gcc/tree.h:3225:11: error: identifier =E2=80=98thread_local=E2= =80=99 conflicts with C++ keyword [-Werror=3Dc++-compat] so I suppose that's OK. However, the bug was reported for host x86_64-unknown-linux-gnu, so we need= to test with a recent compiler bootstrapped on that host to verify. Our optimizers often behave differently with differently sized HOST_WIDE_IN= T.
