I tried this out twice, just to make sure, but after the last 1861 svn update,
(today) the compile is not building the zone app.
I did a successful compile on the previous update (1857) just to make sure
nothing special was happening on my end, but I was actually suprised to see
unsuccessful compile, as it has been going smooth with the updates for a long
time now

I am not sure what to look for in the build log, but if you need it posted here
I can do that, as well.
EDIT:
The only errors I seen while it was building zone, was the following in spells.cpp :
3>.\spells.cpp(146
: error C2661: 'Raid::GetGroup' : no overloaded function takes 0 arguments
3>.\spells.cpp(1480) : error C2661: 'Raid::GetGroup' : no overloaded function takes 0 arguments
3>.\spells.cpp(1492) : error C2661: 'Raid::GetGroup' : no overloaded function takes 0 arguments
3>.\spells.cpp(1504) : error C2661: 'Raid::GetGroup' : no overloaded function takes 0 arguments
I hope this helps.
