 There is one case where C++ style comment create a useful feature that I
 don't believe C style comments are able to replicate. Some might disagree.
 In a color syntax highlighting editor in a C99 codebase, you can prefix C
 style comments with C++ style comments and get single character feature

   //* Remove first / to disable this block

 In a color syntax highlighting editor, doSomething(); takes on normal
 highlighting when enabled, and takes on comment colored highlighting when
 disabled. Visually, that's slightly improved over something like

   #ifdef DEBUG

 where you need to know what defines are created in your codebase, and maybe
 there is a clash with a header or deep in the header chain, and you need to
 know what defines are created on the command line.
