 - Replace the whole u_intXX_t evilness in acconfig.h with something better???
 
+- Consider splitting the u_intXX_t test for sys/bitype.h  into seperate test
+  to allow people to (right/wrongfully) link against Bind directly.
+
 - Move all "openbsd-compat" files to it's own directory.  Consider doing the 
   same with libssh. I don't think we need to split ssh, sshd, etc into their 
   own directory.
