++/* In C (but not C++), mpfr_ptr and mpfr_srcptr arguments can be provided
++ in a different pointer type, such as void *. For functions implemented
++ as macros, the type conversion for the function parameters will not be
++ done by the compiler, which means potential bugs in these implementations
++ if we forget to take these unusual cases into account. So we need to test
++ such arguments, in order to make sure that the arguments are converted to
++ the expected type when needed.
++
++ However, at least when the function is not implemented as a macro (which
++ is the case when MPFR_USE_NO_MACRO is defined), such tests with void *
++ arguments are not valid in C++; therefore, we will not do the cast to
++ void * if the __cplusplus macro is defined. And with GCC compilers (and
++ compatible), we will ignore the -Wc++-compat option around these tests.
++
++ Note: in the future, inline functions could be used instead of macros,
++ and such tests would become useless (except to detect compiler bugs).
