This patch contains:
-random bugfixes
-gcc -Wall "fixes"
-a few new constants for 4.x
-Implementation of virConnectAuth
-javah build fixes (One .class file can generate many .h files.)
It is NOT a full update for 4.x, the only major new feature is
authentication support.
I've attached the patch, and the new files. (Is there some way to
generate patches with new files?)
Please remove the
/src/jni/org_libvirt_VirDomain_CreateFlags.h
/src/jni/org_libvirt_VirDomain_MigrateFlags.h
files from the CVS, as these are auto-generated.
regards
István
