Latest version of xcode Command Line tools breaks sparsehash. about sparsehash HOT 6 OPEN

I tried "make check" on sparsehash on a Mac with the latest xcode. It didn't 
work. The attached patch was able to fix 3 warnings and, more seriously, a type 
incompatibility.

I'm not ready to commit the patch yet (though I suspect it would be fine), and 
it may take me a week or two to get to it. But, the patch is here if you want 
to try it.

I now see that the patch mentioned in issue 100 is pretty much the same thing. 
Thanks Meno!

Issue 100 has been merged into this issue.

Is the fix going to be merged to master?

Correct me if I'm wrong, but I suspect the root cause was that 
sparse_hashtable_iterator::st_iterator, 
sparse_hashtable_const_iterator::st_iterator, and 
sparse_hashtable_destructive_iterator::st_iterator were not typedef-ef 
correctly. So I propose the following patch for the type incompatibility issue 
instead.

there are a number of warning in the unit tests after applying the patch, but 
otherwise is excellent
