UNIX style SYSLOG can be enabled via the flag SYSLOG_FLAG. This will send 
logging information to a SYSLOG specified destination. By setting this flag
to a non-zero value, SYSLOG information will be automatically generated.

The defines for this are stored in the file diplog.h, currently only the
log level of LOG_USER is hard-coded.

All syslog levels can be used, and are available via variable-argument
functions, namely:

void DIPERROR(char *fmt, ...);
void DIPWARN(char *fmt, ...);
void DIPNOTICE(char *fmt, ...);
void DIPINFO(char *fmt, ...);
void DIPDEBUG(char *fmt, ...);

in decreasing order of severity. Only a few calls are made at present to 
these functions, these should be expanded in the future.
