The "define uint64_t unsigned long long" were too good to work. With a different toolchain I am getting: cstdint:69:11: error: expected unqualified-id using ::uint64_t; ^ executor/common.h:34:18: note: expanded from macro 'uint64_t' Do it the proper way: introduce uint64/32/16/8 types and use them. pkg/csource then does s/uint64/uint64_t/ to not clutter code with additional typedefs.
