'utmp.h' and 'utmp'

[Eddie Wednesday <eddie@cc.nctu.edu.tw>]

Hi !

   While I install a BBS software called PowerBBS. I encounter a problem :
when the system compiler to a file called 'ttysrc.c' ,it told me a message
that it can't find 'utmpx.h' Oh ! My God ! I can't find this file either.

ttysrc.c

Can somebody tell me how to manager this problem !!
