 CHANGE LOG for Independent JPEG Group's JPEG software
 
 
+Version 9c  14-Jan-2018
+-----------------------
+
+jpegtran: add an option to the -wipe switch to fill the region
+with the average of adjacent blocks, instead of gray out.
+Thank to Caitlyn Feddock and Maddie Ziegler for inspiration.
+
+Make range extension bits adjustable (in jpegint.h).
+Thank to Robin Watts for suggestion.
+
+Provide macros for fflush() and ferror() in jinclude.h in order
+to facilitate adaption by applications using an own FILE class.
+Thank to Gerhard Huber for suggestion.
+
+Add libjpeg pkg-config file.  Thank to Mark Lavi, Vincent Torri,
+Patrick McMunn, and Huw Davies for suggestion.
+
+Add sanity checks in cjpeg image reader modules.
+Thank to Bingchang, Liu for reports.

+# 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
+# manager file.  For NT we suggest jmemnobs.obj, which expects the OS to
+# provide adequate virtual memory.
+SYSDEPMEM= jmemnobs.obj
