+# Makefile for Independent JPEG Group's software
+
+# This makefile is for Microsoft Visual C++ on Windows NT (and 95?).
+# It builds the IJG library as a statically linkable library (.LIB),
+# and builds the sample applications as console-mode apps.
+# Thanks to Xingong Chang, Raymond Everly and others.
+
+# Read installation instructions before saying "nmake" !!
+# To build an optimized library without debug info, say "nmake nodebug=1".
+
+# Pull in standard variable definitions
+#!include <win32.mak>
+
+# You may want to adjust these compiler options:
+CFLAGS= $(cflags) $(cdebug) $(cvars) -I.
+# Generally, we recommend defining any configuration symbols in jconfig.h,
+# NOT via -D switches here.
+
+# Link-time options:
+LDFLAGS= $(ldebug) $(conlflags)
+
+# To link any special libraries, add the necessary commands here.
+LDLIBS= $(conlibs)

+# Put here the object file name for the correct system-dependent memory
