After posting that, I realized "unsigned _int64" would not be valid
if _int64 is a typedef. However, GCC 4.7.1 does allow it in C++
(although not in C) and generates the corresponding unsigned type.
Is that another extension? I didn't find any mention of it among
the C++ extensions in the GCC manual.
