> Some incompatibilities have been removed by the latest (C99) C standard,
> which now supports C++ features such as // comments and mixed declarations
> and code. However, C99 introduced a number of new features that C++ does
> not support (such as variable-length arrays, native complex-number types,
> and compound literals), so the languages may be diverging more than they
> are converging. (However, at least some of the new C99 features will
> likely be included in the next version of the C++ standard, C++0x.)
