------- Additional Comments from Filip Pizlo <fpizlo at apple.com>
Corrected the comment.

Apparently, the requirements for return types of functions with C linkage match
the C++-03 definition of POD (a strict subset of aggregate types - so no
C++-style members, only POD fields).  The C++-11 definition has been split up
into two separate concepts (trivial and standard-layout).  Prior to this code
we were returning standard-layout but not non-trivial (and thus not POD)
classes, which is correct in C++-11 but not C++-03.
