The bug in not in the preprocessor.  Remember: the C preprocessor
knows no C.  It does not care what you feed it.  It is used for
assembly code in the 4BSD kernell, for example.

Anyway, to answer the question, the 4.2 compiler mishandles `void';
the 4.3 compiler does not.  Donn Seeley (of F77 compiler fame) fixed
it.  (Thanks, Donn.)
