Fix linking with Sun CC 5.9: function pointers for extern "C" are treated differently
The Sun CC compiler treats C functions and C++ functions differently,
as if they had a different calling sequence (they don't, but they
could). So if you declare a function in C++ having a function pointer
as a parameter, it's understood to be C++ even if it had previously
been declared as extern "C".
This could be a compiler error, though. In any case, the end result is
that WebKit fails to link because of an undefined reference to
NPN_PluginThreadAsyncCall.
"plugins/npapi.cpp", line 177: Warning (Anachronism): Formal argument 2 of type void(*)(void*) in call to WebCore::PluginMainThreadScheduler::scheduleCall(_NPP*, void(*)(void*), void*) is being passed extern "C" void(*)(void*).
There are more of these errors left in WebKit, but they are not
causing problems right now.
