problem of adding a new option of sshd

[kai_yang2008]

Dear all,
 
I want to add a new option "newoption"  to the sshd server, I have just add some codes in servconf.h and 
servconf.c like the other options. But it seems that the "newoption" can not be enable,when i set
the "newoption" to "yes" in sshd_config file. I have add a debug message in main function of sshd.c
....
debug("main sshd %d",options->newoption);
...
 
debug1: main sshd 0
 
>From the debug message, it seems that the "newoption" is not enable.
So could anyone give me some advise about it?
