[PATCH] Use pppd.h provided by ppp-dev
Christoph Biedl <sourceforge.bnwi <at> manchmal.in-ulm.de>
2013-02-06 23:42:48 GMT
I'm not sure about that one, see the Debian bug report for details.
Appearently at some time in the past the shipped plugins/pppd.h did
not match any longer, so the one provided by the ppp-dev package is
used instead. Does this make sense in upstream, too?
Description: Use pppd.h provided by ppp-dev
