// g++ 1.37.1 bug 900321_01

// cfront flags ERRORs on each of the lines indicated below. g++ does not
// flag either ERRORs or warnings.

// Although I cannot find where in the current C++ Reference Manual this
// topic is covered, I am sure that these statements should get ERRORs in
// a "strongly typed" language.

// Cfront 2.0 passes this test.

// keywords: array types, array bound, pointers
