Strongly in favour - I've been pondering on this for a very long time.
Just a question - is there a compiler that care about (something from
the last decade) that does not define __cplusplus but c_plusplus ?

Afaict the former is defined since (at least) the 1998 C++ standard,
while the latter is extremely rare, and mostly mentioned as decrecated.

I don't know, this was just copy paste from other file.

For me it is ok to drop c_plusplus, no strong opinion.
