# What you can define:
# -DDEBUG		enables debugging facilities:
#			you can increment debug level with debug keyword in
#			config file, -d option, or by sending SIGUSR1 to init.
#			SIGUSR2 sets debug level to 0.
# -DUNTRUSTED		debugging code: on SIGINT it execs /sbin/init.ori
#			(do this only in singleuser mode !)
# -DCONFIGURE		on startup (and when requested), read /etc/init.conf
#			and set parameters in it.
# -DFAKE_SYSLOG		do not use syslog, but write to /dev/console.
#			This makes it MUCH smaller !
# -DSMALL		do not use perror, but write error codes.
#			Makes it even smaller, but requires -DFAKE_SYSLOG.
# For the floppy version, compile this with -DFAKE_SYSLOG -DSMALL. If compiled
# with gcc1, it is not bigger than the original init (20k).
