| * Bug 689101 - jsval is technically a non-POD type because it has a private |
| * data member. On gcc, this doesn't seem to matter. On MSVC, this prevents |
| * returning a jsval from a function between C and C++ because it will use a |
| * retparam in C++ and a direct return value in C. |
| * |
| * Bug 712289 - jsval alignment was different on 32-bit platforms between C and |
| * C++ because the default alignments of js::Value and jsval_layout differ. |
