The exit code on windows is stored in a DWORD, an unsigned long:
<https://docs.microsoft.com/en-us/openspecs/windows_protocols/ms-dtyp/262627d8-3418-4627-9218-4ffe110850b2>
Use the max value of this type for SC_EXIT_CODE_NONE.
// <https://stackoverflow.com/a/44383330/1987178>
# define SC_PRIsizet "Iu"
# define SC_PROCESS_NONE NULL
-# define SC_EXIT_CODE_NONE -1u // max value as unsigned
+# define SC_EXIT_CODE_NONE -1UL // max value as unsigned long
typedef HANDLE sc_pid;
typedef DWORD sc_exit_code;
typedef HANDLE sc_pipe;
