Reopening because gcc-4.4 still reports a gazillion issues.  Here are the
first two:

clang/lib/Basic/../../include/clang/Basic/SourceLocation.h: In member function
‘bool clang::SourceManager::isBeforeInTranslationUnit(clang::SourceLocation,
clang::SourceLocation) const’:
clang/lib/Basic/../../include/clang/Basic/SourceLocation.h:43: warning:
dereferencing pointer ‘<anonymous>’ does break strict-aliasing rules
/usr/include/c++/4.4/bits/stl_tree.h:175: note: initialized from here
...
clang/lib/Parse/../../include/clang/Parse/DeclSpec.h: In member function
‘clang::CXXScopeSpec&
clang::DeclaratorChunk::MemberPointerTypeInfo::Scope()’:
clang/lib/Parse/../../include/clang/Parse/DeclSpec.h:637: warning:
dereferencing type-punned pointer will break strict-aliasing rules
