If we are being used with glibc, we need to include <features.h>, but
that does not exist if we are standalone. So: if __GNU_LIBRARY__ is
- not defined, include <stdlib.h>, which will pull in <features.h> for us
- if it's from glibc (and will declare getopt). Fall back on <ctype.h> if
- <stdlib.h> might not exist. (Why ctype.h? It's guaranteed to exist and it

doesn't flood the namespace with stuff the way some other headers do.) */
