Comment (by devans@…):

 Using your patch, I was able to build webkit-gtk3 on Mavericks as
 expected.  But, also as expected, I ran into problems building on ML with
 this error:

 {{{

 This is a 'needs libc++' issue: std::move is not available in libstdc++.

 After adding -stdlib=libc++ to both CXXFLAGS and LDFLAGS, the build
 proceeded and I got a successful build after
 one further minor patch concerning the path name for freetype.h.

 Attached is an additional set of patches that encapsulates these changes
 and allows the build on ML. This should work as long as Xcode 5 is
 available.

 Not sure about Lion and certainly SL and earlier remain a problem.

 So looks like the issues are:

  * needs a C+11 capable compiler
  * needs libc++

 What's the best way to do this on the earlier platforms?
