user defined conversion to void

[Stefan Schwarzer <sts at ica1 dot uni-stuttgart dot de>]

//
// the standard allows conversion functions (12.3.2) with the form 
// operator type-specifier-seq ()
// now from the grammar summary one figures out that 'void' is a 
// correct type-specifier-seq
// although it is not terribly useful (12.3.2.1) one 
// is allowed to declare such 
// functions (footnote 103)

// gcc-2.95.2 should thus compile this code
