# Do not build with IPv6 support.
# By default, IPv6 support is compiled in on platforms that
# are known to have IPv6 support.

# Note: this directive is for debugging and testing only. It
# is not guaranteed to work on all platforms
Trying to build postfix with:
$ make 'CCARGS= -DNO_IPV6 -DHAS_CDB -I/usr/include/cdb' 'AUXLIBS=-Wl,-O1
-Wl,--as-needed -lcdb' makefiles && make
results in:
[...]
gcc -Wmissing-prototypes -Wformat -DNO_IPV6 -DHAS_CDB -I/usr/include/cdb
-DHAS_PCRE -DSNAPSHOT -g -O -I. -DLINUX3 -c cidr_match.c
