Setting the CPPFLAGS environment variable before running configure
can be used to enable certain compile-time options that are not
explicitly defined in configure.
Some of these settings are:

|---|---|
-DCHECK_LOCAL=0 |

Don't check sibling glue in named-checkzone |
-DISC_FACILITY=LOG_LOCAL0 |
Change the default syslog facility for named |
-DISC_HEAP_CHECK |
Test heap consistency after every heap operation; used when debugging |
-DISC_MEM_DEFAULTFILL=1 |
Overwrite memory with tag values when allocating or freeing it; this impairs performance but makes debugging of memory problems easier |
-DISC_MEM_TRACKLINES=0 |
Don't track memory allocations by file and line number; this improves performance but makes debugging more difficult |
-DNAMED_RUN_PID_DIR=0 |
Create default PID files in ${localstatedir}/run rather than ${localstatedir}/run/named/ |
-DNS_CLIENT_DROPPORT=0 |
Disable dropping queries from particular well-known ports |
-DOPENSSL_API_COMPAT=10100 |
