long long, as a built-in type, is available in g++ by default. It is
an extension that cannot be mistaken as a well-formed C++ program, so
-ansi has nothing to do with it. In g++, this type is not available
with -pedantic. I'd prefer if this strategy (provide extensions by
default) also applies to the libraries included in GCC.
