# Makefile to build XZ Utils using DJGPP
#
# Make flags to alter compilation:
#
#   DEBUG=1     Enable assertions. Don't use this for production builds!
#               You may also want to set CFLAGS="-g -O0" to disable
#               optimizations.
#
# The usual CPPFLAGS and CFLAGS are supported too.
