Please either rename the file or the guard definition.

[Dai Mikurube (NOT FULLTIME), 2012/08/07 10:39:18]

Done.

+#define BASE_ALLOCATOR_ALLOCATED_TYPE_INTERCEPT_H_
+
+#include <cstddef>
+#include <typeinfo>
+
+void* __op_new_intercept__(void*, size_t, const std::type_info&);

nit: Declarations should have variable names, matching that seen in the
definition.

[Dai Mikurube (NOT FULLTIME), 2012/08/03 10:01:50]

Done.

+void* __op_delete_intercept__(void*, size_t, const std::type_info &);

These functions are inserted around all 'new' and 'delete' expressions by the
compiler option '-fintercept-allocation-functions' introduced in
http://crrev.com/149572.

If you need to clarify something about the change, please write a comment in the
code.

[Dai Mikurube (NOT FULLTIME), 2012/08/02 16:14:35]

Ok, I'll do that.  (I added these codereview comments just before leaving.  I
didn't have time to re-upload.)

[Dai Mikurube (NOT FULLTIME), 2012/08/03 10:01:50]

Done.
