This function is missing on some platforms:
NetBSD 3.0, HP-UX 11, IRIX 6.5, Solaris 9, mingw.

glibc has an incompatible version of this function.  The POSIX compliant code
@smallexample
char *s = (strerror_r (err, buf, buflen) == 0 ? buf : NULL);
@end smallexample
is essentially equivalent to this code using the glibc function:
@smallexample
char *s = strerror_r (err, buf, buflen);
@end smallexample
