+ #include <string.h>
+ #include <ctype.h>
+ #define _GNU_SOURCE
++#define __USE_GNU

My understanding was that code outside of the C library should never
define __USE_GNU, as it's an internal implementation detail. The real
problem appears to be that it's not getting implicitly defined via
_GNU_SOURCE, because the existing definition is in the wrong place - it
should be before the first #include.
