Stephen already explained the whys and wherefores, so I'll just paste
the patch in here for public consideration.
Obviously I'm +1 on the patch in theory, and building works for my
standard build with Apple clang (C++ *and* C) on Yosemite.
Note that Clang complains that building C code with a C++ compiler is
a "deprecated behavior". Has anybody heard about this? Are there
changes in the offing that will make C code that is acceptable to a
C++ compiler unusably restricted?
