Instance Parent .cpp build with GCC 4 .6
On Ubuntu 12.04, gcc 4.6.3, I get this build error: /hack/mozilla-central/dom/plugins/ipc/PluginInstanceParent.cpp: In member function ‘virtual bool mozilla::plugins::PluginInstanceParent::AnswerNPN_SetValue_NPPVpluginDrawingModel(const int&, mozilla::plugins::PPluginInstanceParent::OptionalShmem*, mozilla::plugins::PPluginInstanceParent::CrossProcessMutexHandle*, NPError*)’: /hack/mozilla-central/dom/plugins/ipc/PluginInstanceParent.cpp:453:46: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast] cc1plus: all warnings being treated as errors WARNINGS_AS_ERRORS has been enabled there by bug 743573. The code here sucks: there is no valid use case for converting integers of smaller sizes to pointers. If a universal untyped storage of the size of a pointer is wanted, void* is not the right type to use for that. uintptr_t would be it. hg annotate is unable to find the author of this code, as it hits a big merge first, 17c65d32c7b891e70435561b965b71c355bd28ac, by BenWa.

Comment on attachment 650573 [details] [diff] [review] fix the build I don't understand the second paragraph of your rant; we're dealing with a frozen NPAPI call here which specifies a void* and then sometimes passes numbers through it. We should just make the cast and not fret.

If the NPAPI interface requires that void*, I shall direct my ranting against NPAPI instead of the author of this code.
