Somebody posts this code that fails one a 4BSD VAX:

The dpANS [May88] says this is OK.  Look in the Language Syntax Summary
in Appendix A and focus on `initializer' (bottom of p 180).  Follow it up
the path and you'll hit || and &&.  I didn't see any constraints that
would prevent this, and my compiler takes it as well.
