For things like C and C++, which have widely recognized ISO
standards, I don't mind taking the established rules as being
authoritative, and acting accordingly.

For tools like gcc or g++ or clang, which depend on the whims of
whichever developers happen to be contributing, and which easily
may change from one version to another, my usual practice is to
spell things out more explicitly.  Here I think it helps convey
the point if the -x c and -x c++ options are made explicit rather
than being left as implied.
