make courier-imap-4.1.3时出现以上错误,参考了这篇文章:
http://blog.chinaunix.net/opera/showart.php?blogid=12199&id=63734
文章作者所用操作戏台是debian,我用的是RHEL AS 4.0

根据实际 , 修改/tmp/courier-imap-4.1.3/imap下的Makefile
CFLAGS = -I.. -I./.. -Wall -g -O2
修改为
CFLAGS = -I/usr/local/courier-authlib/include -I.. -I./.. -Wall -g -O2

这样就可以make通过了
