Given that it does *not* catch the IMHO most annoying issue it appears to
be rather useless. The one common thing it catches - i.e. single line
comments - is accepted by all compilers I use ...

5.24 Mixed Declarations and Code
================================

ISO C99 and ISO C++ allow declarations and code to be freely mixed
within compound statements.  As an extension, GCC also allows this in
C89 mode.  For example, you could do:

     int i;
     /* ... */
     i++;
     int j = i + 2;

   Each identifier is visible from where it is declared until the end of
the enclosing block.                                    [gcc-3.3.5 info]
