       Make build shut up about system() without return value check.
       
           st.c:1321:2: warning: ignoring return value of function declared with warn_unused_result attribute [-Wunused-result]
                   system(cmd);
                   ^~~~~~ ~~~
       
       Debatable whether an error here should case exit(EXIT_FAILURE). Just
