Thanks for that information. I'd be interested to know what C++ features
are no longer supported.
Fortunately for my work, support for compiling C as C++ has not been
dropped entirely, or perhaps it's just been reinstated unofficially. For
example, make maintainer-check runs all test cases with a C++ compiler.
Also, in recent months, I've seen effort to cast the return of malloc
because C++ doesn't allow assigning a void* to a non-void* type. On the
other hand, this cast is actually considered by some to be bad style in C:
if you forget to #include the prototype for malloc, the cast prevents the
compiler from warning you that the assumed int return type of malloc is
unreasonable.
