            Bug ID: 16336
           Summary: Warning for 'register' is too noisy
           Product: clang
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++11
          Assignee: unassignedclangbugs at nondot.org
          Reporter: steveire at gmail.com
                CC: dgregor at apple.com, llvmbugs at cs.uiuc.edu
    Classification: Unclassified

It seems that it is used in common system headers. There should probably at
least be a standalone flag to disable it like -Wno-register
