I don't think this solution is portable to any C compiler.  Because the ordering
of local variables is very dependent of the implementation of compilers, for
example, Visual C++ by Microsoft.  I don't know the current version of GCC
compiler preserves the ordering of local variables. Therefore, I implemented
ProPolice at the intermediate language level.
