# Makefile for Linux 2.xx.xx systems.
# This file will only be picked up by GNU make.  It will assume
# that gcc exists.
# Slight modifications should make it possible for this to
# work on other OS's.
# By default this makefile makes a large executable with debugging
# information.  There are optim, profile and archaic options.

# Changes you might have to make to password encryption work:
#	1. remove -lcrypt from LINKLIB line
#	2. use crypt.c: add crypt.c to the C_FILES
# Try step 1 first, and if that doesn't work, try step 2.

### Choose the option you want to use from the three below, only one can
# be chosen, the preferred one is to have debugging enabled.
# FYI, you can actually use -g3 -O, it still works well in the debugger
# and is somewhat optimised, but the compiler works pretty hard.
