This change causes problems:

  Inetutils, http://hydra.nixos.org/build/617935
  libunistring, http://hydra.nixos.org/build/618008
  Octave, http://hydra.nixos.org/build/618125
  ...

The error is:

--8<---------------cut here---------------start------------->8---
./wctype.h:581:14: error: operator '||' has no right operand
./wctype.h:654:6: error: #if with no expression
--8<---------------cut here---------------end--------------->8---

My guess is that this is due to a typo: ‘gl_WCTYPE_H’ sets
‘REPLACE_HAVE_ISWBLANK’ instead of ‘REPLACE_ISWBLANK’.

Thanks,
Ludo’.
