There are a substantial, and growing, number of incompatibilities
between standard C and standard C++. Attempting to write C which can
be compiled by a C++ compiler is, IMO, a waste of time.
The C spec reserves "for any use" symbols beginning with _[A-Z_], and
global (linker-visible) symbols beginning with _[a-z0-9]. In
practice, the C library sticks to the _[A-Z_] namespace. I haven't
had any problems using _cpp_ as a tag for non-static symbols private
