Are you sure you're using clang++? I get the same error when I use
"clang -c test.h", but when I use "clang++ -c test.h" it compiles the
header just fine (though it does warn about treating a 'c-header' as
'c++-header' in C++ mode).

-std=gnu89 turns on GNU C mode, not GNU C++ mode. Try -std=c++98 or
-std=gnu++98 if you're using clang instead of clang++.
