Clang applies the missing-prototypes warning on C++ files, whereas
gcc only applies it to C. As a result, the decklink_common.cpp file
fails to build because of missing prototypes in DecklinkDispatch.cpp
(which is #included by decklink_common.cpp).
We don't want to change the actual Blackmagic SDK sources, so
suppress the warning just for that one #include.
