The One Character Block Comment

This is also an old trick to test whether your code was compiled as a C++ or not:

  2//**/2
    == 1) ? "C" : "C++"

This is fun and has some hack value but I hope nobody ever uses such a kludge in real code.

It totally fails with crappy C compilers that decide to feature C++ comments unannounced. IIRC gcc does this unless you give -ansi or -std=c89. And C99 officially supports the // -comments but hasn't got C++ features, of course.

Is there a situation where you would need this instead of "#ifdef __cplusplus"?

No. It's just for hack value.
