Hi,

Building glibc fails at least on s390/power with:
connections.c: In function ‘restart’:
connections.c:1467:4: error: implicit declaration of function 
‘ignore_value’ [-Werror=implicit-function-declaration]
     ignore_value (setuid (server_uid));
     ^
cc1: some warnings being treated as errors

Including libc-internal.h fixes the build failure.

Bye
Stefan

	* nscd/connections.c: Include libc-internal.h
	  because of macro usage ignore_value.
