安装jpeg library显示jconfig.h is unchanged，求高手帮忙！
在cygwin（Unix）下安装了jpeg library，但是无法creating jconfig.h

creating ./config.status
creating Makefile
creating jconfig.h
jconfig.h is unchanged
看install.doc上说，If you are on a Unix machine, you may not need to read this file at all.
Try doing
./configure
可是运行./configure后，卡在了jconfig.h is unchanged，请求高手解答一下菜鸟的问题，万分感谢！！！！！！ jpeg?library Uinx cygwin

到这个文件./configure看看，“jconfig.h is unchanged”是怎么回事，看上面好像已经生成Makefile了，是不是已经可以编译安装了
[解决办法]
意思是编辑configure，看看jconfig.h is unchanged是什么原因导致的；
或者找到jconfig.h，换个名字备个份，再./configure看还是不是报jconfig.h is unchanged
再说，creating Makefile // 这里不是生成了makefile了么；
