Related, does gcc forbid "long long" / ULL ? In a recent similar GDB discussion, I noticed that libdecnumber seems to uses both unconditionally (for UINT64, and e.g., the initialization of reciprocals10_128). So if libdecnumber is always built with gcc, gcc is also already depending on "long long" / ULL being available too. -- Pedro Alves
