I would like to upgrade my openSUSE 11.3 x64 (dial-in) server to openSUSE 12.2 x64.

11.3 settings:
/AutoPPP/ - a_ppp /usr/sbin/pppd -chap +pap login debug
* - - /bin/login @

But, when connected the modem, the autoPPP not working.
The login.config containing:
# Automatic PPP startup on receipt of LCP configure request (AutoPPP).
# mgetty has to be compiled with "-DAUTO_PPP" for this to work.

How to compiled the mgetty with "-DAUTO_PPP" ???

( I tried to copy /usr/sbin/mgetty from version:11.3 to 12.2 and how it works for all.
I do not see this as the best solution. )

( sorry my english )
