// { dg-do assemble  }

// g++ 1.36.1 bug 900205_03

// Section 6.6.3 of the cfront 2.0 Reference Manual says "A return statement
// without an expression can be used only in functions that do not return
// a value, that is, a function with the return value type void..."

// Also in 6.6.3: "Flowing off the end of a function is equivalent to a
// return with no value; this is illegal in a value returning function."

// In contrast to the manual, g++ does not generate ERRORs for cases of
// "flowing off the end" of non-void functions.

// keywords: return statements, return type, void return, implicit return
