POSIX does NOT specify getsubopt() to use 'restrict'.
However, glibc uses 'restrict'.
Users might be surprised by this! Let's use it here too!
.../glibc$ grep_glibc_prototype getsubopt
stdlib/stdlib.h:958:
extern int getsubopt (char **__restrict __optionp,
char *const *__restrict __tokens,
char **__restrict __valuep)
__THROW __nonnull ((1, 2, 3)) __wur;
