But functions declared as extern "C" aren't C functions.  They're C++
functions that happen to use a C calling convention.  They obey the
C++ language rules in every way, and they may use C++ language
features freely.

The C++ standard does not provide a mechanism for compiling C code
within a C++ translation unit.
