Yes, that's not what I meant.  My question is that ISTR that Automake
supports `missing'ing yacc, and we must make sure that in this case
`bison -y' is properly passed as two entities.

|   $ p=:

|   º: not found

| 
|   $

Aha!  It is the 8th bit problem again.  Then try this:

p=":"
"$p"

maybe it will work.  No guarantee, but as shocking as it may seem, I
wouldn't be surprised that it works.

The difference might be that with `echo' it had to look in PATH, if
it's not a build in.  Then, we can imagine plenty of places where the
8th big is reversed again.  Give a try to `cd' as it must be a
builtin.

In fact, does

":"

alone, work?
