# Makefile for bunzip2 for GNO (for use with dmake)
# Based on Unix Makefile for bzip2
# Modified for GNO by Stephen Heumann

# ORCA/C 2.1.0 may need more than 8 megabytes of RAM to compile decompress.c
# with full optimization enabled.  Thus, this makefile can only
# be used as is on an emulated system with 14 megabyte RAM support.

# To assist in cross-compiling
# Uncomment this if make doesn't have the $CC variable set appropriately
# CC=occ
RM=cp -p rm

LDFLAGS=

# The "-I /usr/include" shouldn't be needed but seemed to fix problems for me
CFLAGS=-a0 -w -O -I /usr/include

NOROOTFLAG=-r

# Where you want it installed when you do 'make install'
