Submitted a patch to the ML to do just that.

Oh, I must have been looking at master.  In commit 4a99b0023[1] this was
changed to:

    MACOS = 0
    ifneq (,$(findstring Darwin,$(shell uname)))
    	MACOS = 1
    	ifneq (,$(findstring 13,$(shell uname -r)))
    		CPP = clang++
    		CC = clang
    		EXTRA_FLAGS += -stdlib=libstdc++
    	endif
    endif

I'm not sure why it built the first time, though.  (Compare [2] and
[3], both using the same release.)  Anyway, I can go ahead and patch the
Makefile until a new release is out.

What do you think?
