+Subject: [4.0.x] may reach end warning in system headers
+Message-Id: <20050701183024.E138714C16A9@geoffk5.apple.com>

+
+
+One of our users was getting
+
+/usr/include/gcc/darwin/4.0/c++/bits/stl_uninitialized.h:113: warning:
+control may reach end of non-void function '_ForwardIterator
+std::__uninitialized_copy_aux(_InputIterator, _InputIterator,
+_ForwardIterator, __false_type) [with _InputIterator =
+__gnu_cxx::__normal_iterator<TPoolAllocator::tAllocState*,
+std::vector<TPoolAllocator::tAllocState,
+std::allocator<TPoolAllocator::tAllocState> > >, _ForwardIterator =
+__gnu_cxx::__normal_iterator<TPoolAllocator::tAllocState*,
+std::vector<TPoolAllocator::tAllocState,
+std::allocator<TPoolAllocator::tAllocState> > >]' being inlined
+
+which shouldn't be happening, he has no way to change a standard C++
+header.  The warning is bogus anyway, but it's fixed in 4.1 through
+the CFG changes, which I don't really want to backport to the 4.0
+branch, so instead I'll add this patch.  Other warnings generated from
+tree-inline.c check for DECL_SYSTEM_HEADER like this.
+
+Bootstrapped & tested on powerpc-darwin8, I'll commit when the branch
+is unfrozen.
