4768. [func] By default, memory is no longer filled with tag values when it is allocated or freed; this improves performance but makes debugging of certain memory issues more difficult. "named -M fill" turns memory filling back on. (Building "configure --enable-developer", turns memory fill on by default again; it can then be disabled with "named -M nofill".) [RT #45123]

Setting the STD_CDEFINES 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:
| Setting | Description |
|---|---|
-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. |
-DISC_FACILITY=LOG_LOCAL0 |
Change the default syslog facility for named |
-DNS_CLIENT_DROPPORT=0 |
Disable dropping queries from particular well-known ports: |
-DCHECK_SIBLING=0 |
Don't check sibling glue in named-checkzone |
-DCHECK_LOCAL=0 |
Don't check out-of-zone addresses in named-checkzone |
-DNS_RUN_PID_DIR=0 |
Create default PID files in ${localstatedir}/run rather than ${localstatedir}/run/named/ |
