compilation errors from Xcode's new standard library

[Mike Solomon]

Looks like some files in flower don't play nice with the most recent version of 
the standard library bundled with Xcode…

Going through the standard library files in question, here are some snippets…
I’ve added comments next to the problematic lines

/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/c++/v1/vector
<snip>
template <class _Tp, class _Allocator>
_LIBCPP_INLINE_VISIBILITY inline
typename vector<_Tp, _Allocator>::iterator
vector<_Tp, _Allocator>::__make_iter(pointer __p) _NOEXCEPT
{
#if _LIBCPP_DEBUG_LEVEL >= 2
    return iterator(this, __p);
#else
    return iterator(__p); // MS  - this is where g++ freaks out
#endif
}
</snip>

and then…
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/lib/c++/v1/iterator
<snip>
private:
    _LIBCPP_INLINE_VISIBILITY __wrap_iter(iterator_type __x) _NOEXCEPT : 
__i(__x) {} // MS  - this is where g++ freaks out
#if _LIBCPP_DEBUG_LEVEL >= 2
    _LIBCPP_INLINE_VISIBILITY __wrap_iter(const void* __p, iterator_type __x) : 
__i(__x)
    {
        __get_db()->__insert_ic(this, __p);
    }
#endif
 

</snip>

Any ideas for how to proceed?

Cheers,
MS
