By the way, re cpp: the V7 "cpy.y" has bugs in the actions for the
!, ~, and - rules: they should read $$ = $2
instead of $$ = $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".
