Subject: [PATCH] Fix m68k __sync_lock_test_and_set_1 definition
Date: Fri, 17 Aug 2012 14:34:29 +0200
List-Archive: <http://gcc.gnu.org/ml/gcc-patches/>

This fixes a warning about the definition not matching the builtin.
Since the type is not actually used for accessing the data, this doesn't
affect the generated code.

Tested on m68k-linux and committed.

Andreas.
