Thank you, it works on Solaris 10, but I strongly suspect it might
fail on Solaris 11 (I can test that as well) as well as on random
other platforms that might lack the function. To me this doesn't look
like the correct solution, it would be much better to do it in a
similar way as for example in gnuplot where configure.ac contains
    AC_CHECK_FUNCS(... strnlen ...)
and then the code uses

#ifndef HAVE_STRNLEN
size_t
strnlen(const char *str, size_t n)
{
    const char * stop = (char *)memchr(str, '\0', n);
    return stop ? stop - str : n;
}
#endif

A check for Solaris seems strange.
