* __STDC_VERSION__ is undefined when headers are called from C++ code resulting in not using stdint.h and efibind.h "making a guess" on what they are. extern "C" will not define __STDC_VERSION__. * Always leverage stdint.h on C++. * Honestly, gnu-efi should always use stdint.h, or find a better way to detect it. (or platforms without it need to catch up to 2007)
