By the way, re cpp: the V7 "cpy.y" has bugs in the actions for the
!<number>, ~<number>, and -<number> rules: they should read $$ = <op>$2
instead of $$ = <op>$1.  The first two are fixed in the 4.1BSD "cpp", and
the third is fixed in the System III "cpp".  For example, the sequence

#if ((-1)*3) == -3
FOO
#else
BAR
#endif

emits

BAR

on the 4.1BSD "cpp", but

FOO

on the System III "cpp".
