[bug-libunistring] ‘cdefs.h’ missing from the distribution

[Ludovic Courtès]

Hi,

Libunistring fails to build on Hydra:

--8<---------------cut here---------------start------------->8---
gcc -DHAVE_CONFIG_H -DNO_XMALLOC -I. -I..  -I. -I. -I.. -I.. -DIN_LIBUNISTRING 
-DDEPENDS_ON_LIBICONV=1   -g -O2 -c striconveh.c
In file included from striconveh.c:30:
unistr.h:23:29: error: unistring/cdefs.h: No such file or directory
make[2]: *** [config.h] Error 1
--8<---------------cut here---------------end--------------->8---

(See, e.g., http://hydra.nixos.org/build/197472 .)

Apparently ‘cdefs.h’ is missing from the distribution.

Thanks,
Ludo’.
