from netbsd:

Don't require compiling with -DDEBUG to enable debugging messages.  Instead,
add a new option flag "-d", which enables debugging output.  Compile all
of the code that used to be enabled with -DDEBUG unconditionally.  The
amount of extra code is negligable, and all of the tests to check if
debugging is enabled were done regardless of -DDEBUG anyway.  Adjust
SYSLOG() to DTRT if debugging is not enabled.
