Hi,

I just updated my tree to include your latest fixes such as r28064.

I'm still getting this:

                 from
/builds/FreeBSD_HEAD_external_toolchain_gcc/lib/clang/libclangast/../../../contrib/llvm/tools/clang/lib/AST/DeclBase.cpp:14:

                            ^
*** [DeclBase.o] Error code 1

make[6]: stopped in
/builds/FreeBSD_HEAD_external_toolchain_gcc/lib/clang/libclangast

Any ideas?
