Agreed.  Now INSTALL does not have inet6 enabled, but I definitely saw
-DINET6 when the crunched binaries were being compiled.  Ah ftp's
Makefile among others have
CPPFLAGS+= -DINET6

That's not good.  Its better if such Makefiles have say:

INET6?=yes

to indicate that they want it and have a .included .mk file do say:

.if defined(INET6) && ${INET6} == yes
CPPFLAGS+= -DINET6
.endif

then its easier for the crunchgen pass to turn it off.
