// g++ 1.36.1 bug 900127_02

// g++ (mostly) keeps separate name spaces for the declarations of data
// objects and functions.

// This means that a single name may be declared as both a data object and
// a function within a given scope.

// This fact allows programmers to write code which is not portable to the
// Cfront translator (which keeps a single namespace for these entities).

// This can also lead to ambiguity when the & (address-of) operator is used.

// Cfront 2.0 passes this test.

// keywords: name spaces, overloading
