// { dg-do assemble  }
// g++ 1.37.1 bug 900428_02

// g++ fails to issue either errors or warnings (even with -pedantic) for
// attempts to perform either pre or post increment or decrement operations
// on variables which have either pointer-to-void types or pointer-to-function
// types.

// cfront 2.0 passes this test.

// keywords: pointer arithmetic, increment, decrement
