Annoying prototypes for execv* functions in V.4 <sys/unistd.h>

[Ron Guilmette]

If you use and/or sell System V Release 4 you may want to fix up your
<sys/unistd.h> file.

It probably contains:

extern int execv(const char *, char *const *);
extern int execve(const char *, char *const *, char *const *);
extern int execvp(const char *, char *const *);

I'm fairly sure that these declarations should be changed to:

extern int execv(const char *, const char *const *);
extern int execve(const char *, const char *const *, const char *const *);
extern int execvp(const char *, const char *const *);

If your company sells V.4 ports to the general public (either on your
company's own hardware or on somebody else's) I encourage you to fix
this annoying little problem in the systems that your company distributes
to its customers.

Please don't make us all suffer with this annoying glitch.
