Indeed, that is what POSIX requires.

POSIX states:
The string pointed to shall not be modified by the application, but may
be overwritten by a subsequent call to strsignal() or setlocale().
The only reason that the return value is not const char * is because
strsignal predates C89 const. But applications should treat it as const
char anyways.
