>Description:
The src.conf knob WITHOUT_INET6 should disable building IPv6-related
tools and turn off IPv6 support in multi-protocol tools. However,
a lot of tools still ignore the knob and include IPv6 support nevertheless.
This is indicated by the presence of "-DINET6" in the output from
buildworld.
The largest component ignoring WITHOUT_INET6 seems to be
Heimdal/KerberosV, but it's by no means the only one. E.g.,
src/lib/libc/net/Makefile.inc adds -DINET6 to CFLAGS unconditionally,
which is likely to conceal related bugs in utilities.
>How-To-Repeat:
# make buildworld SRC_CONF=/dev/null __MAKE_CONF=/dev/null WITHOUT_INET6=yes >& /tmp/w.out
# fgrep -e -DINET6 /tmp/w.out
4302
# fgrep -e -DINET6 /tmp/w.out | grep -vE 'kerberos|heimdal' | wc -l
3257
# fgrep -e -DINET6 /tmp/w.out | grep -vE 'kerberos|heimdal' | tail
