AC_CXX_OLD_FOR_SCOPING
If the compiler accepts the old for scoping rules (the scope of a variable declared inside the parentheses extends outside the for-body), define HAVE_OLD_FOR_SCOPING. Note that some compilers (notably g++ and egcs) support both new and old rules since they accept the old rules and only generate a warning.
