#
# Ultra-flat Makefile for DJGPP (also works for Cygwin).
# Does NOT depend on or use configure.
#
# Works for simple build but *not* for development (no clean, dist, etc).
# Also, WARNING, no header dependencies are included!
#
# How to compile:
#  make -fMkfiles/Makefile.dj

CFLAGS=-DHAVE_CONFIG_H -IMkfiles/dj -O -I.
