+ [BZ #10545]
+ * sysdeps/pthread/configure.in (libc_cv_forced_unwind): Change
+ link test to a compile test.
+ (libc_cv_c_cleanup): Likewise. Declare puts rather than including
+ <stdio.h>.
+ * sysdeps/pthread/configure: Regenerated.
+
2012-03-07 Ulrich Drepper <drepper@gmail.com>
* Makefile (distribute): Remove variable.
