+# Makefile for Independent JPEG Group's software
+
+# This makefile is suitable for Unix-like systems with non-ANSI compilers.
+# If you have an ANSI compiler, makefile.ansi is a better starting point.

+# Read installation instructions before saying "make" !!

+# The name of your C compiler:
+CC= cc
+
+# You may need to adjust these cc options:
+CFLAGS= -O
+# Generally, we recommend defining any configuration symbols in jconfig.h,
+# NOT via -D switches here.
+# However, any special defines for ansi2knr.c may be included here:
+ANSI2KNRFLAGS= 
+
+# Link-time cc options:
+LDFLAGS= 
+
+# To link any special libraries, add the necessary -l commands here.
+LDLIBS= 
+
+# Put here the object file name for the correct system-dependent memory
+# manager file.  For Unix this is usually jmemnobs.o, but you may want
+# to use jmemansi.o or jmemname.o if you have limited swap space.
+SYSDEPMEM= jmemnobs.o
