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.
