/*
|
|
* 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.
