Grumble, will someone give me all the warnings you want turned on so I
can work around all of them? :)
 
% cat exec.c
 
#include <unistd.h>
#include <paths.h>
#include <string.h>
 
int main(int argc, char *const argv[], char *const envp[]) {
  char *const execargv[] = { strdup(_PATH_BSHELL), strdup(NULL) };
 
  execve(_PATH_BSHELL,execargv,envp);
 
  return 0;
}
% cc -Wwrite-strings -Wcast-qual exec.c
% cc -Wall exec.c
