No need to be sorry about English, but the topic is OK for gcc-help, not
gcc development.
gcc was among the first compilers to support long long (always as 64-bit),
the only problem being that it was a gnu extension for g++. In that form,
the usage may not have settled down until g++ 4.1. The warnings for
attempting long long constants in 32-bit mode, without the LL suffix, have
been a subject of discussion:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=13358The warning doesn't mean that long long could be less than 64 bits; it
means the constant without the LL suffix is less than 64 bits.
