clang patches 205197 or 205198 possibly causing/exposing problems in libcxx with mingw64

Thu Apr 3 00:14:43 PDT 2014

We may need to relax our dllimport checking if we see the GNU __attribute__
spelling of dllimport/dllexport.  GCC typically just smushes attributes on
decls together without checking, and we should be compatible if possible.
