Thanks, Arnold.
However, I don't understand how that patch can make a difference.

Other than comments, lib/hard-locale.h is just this:

  #ifndef HARD_LOCALE_H_
  # define HARD_LOCALE_H_ 1
  # include <stdbool.h>
  bool hard_locale (int);
  #endif /* HARD_LOCALE_H_ */

xalloc.h does not reference "hard_locale"...

What was the compilation failure?
