`bool` is a keyword in C++, and if you want to be able to compile
your C code with a C++ compiler, you obviously can't use `bool`
(or `class`, or `public`, or ...) as an identifier.  But there's
rarely a real need to write C++-compatible C code.  No C compiler
should complain about `int bool;`.  And I'm fairly sure all versions
of Visual Studio include a C compiler.

On the other hand, `bool` is almost certainly a lousy name for
a variable.

Unless the purpose of the declaration was to ensure that the code
wasn't being compiled with a C++ compiler (though I'd use `int
class;` for that).
