Hi Matthieu, I hate to be the bearer of bad tidings, but your latest changes to genauth.c on xf-4_3-branch did not build for me. I had to remove function prototypes that were duplicated in dm_auth.h when HASXDMAUTH is defined.
I also resynced with your latest PAM handling updates in session.c and continued making the C style consistent. The tree builds fine and xdm appears to work with these patches applied. Diff is attached, and is against xf-4_3-branch. -- G. Branden Robinson | Religion is regarded by the common Debian GNU/Linux | people as true, by the wise as [EMAIL PROTECTED] | false, and by the rulers as useful. http://people.debian.org/~branden/ | -- Lucius Annaeus Seneca
