Well,
long long(123456789012345678);
isn't valid C++. Either use cast syntax or provide a typedef.

Yes, you are right, but why libgcc uses #define for __int64 instead of typedef?
This is confusing.

MinGW and MinGW-w64 use #define instead of a typedef, because that allows for
uses like 'signed __int64' and 'unsigned __int64', i.e. __int64 isn't native to
gcc.
