Comment (by kencu):

 Looks like this is a bit more compilicated. This link line:
 {{{

 version-min=10.5 -O2 -DUNICODE -DUNICODE -DSIZE_T_IS_LONG -mmacosx-

 }}}
 hardcodes a link to `-lstdc++` as the final entry. That should not happen.
 We'll have to dig in a bit here and see why that is happening.
