Hi!

On ia64 I get:
../sysdeps/posix/sysconf.c:1215: warning: '__sysconf_check_spec' defined but not used

The following patch seems to cure it.
I tried __attribute__((unused)) first but for some reason that still warned
(maybe compiler bug).  __attribute_used__ is not something that is desirable
in this case, as there is no point in actually having the routine if it will
be never used.

2004-12-07  Jakub Jelinek  <jakub@redhat.com>

	* sysdeps/posix/sysconf.c (__sysconf_check_spec): Only define
	if it will be actually used.
