I'm trying to build pgAdmin from svn using VisualStudio 2005.
It's doing ok until it needs ver.h as referenced by xtra\pgagent\pgaevent\pgamsgevent.rc at line 15.
Ver.h is deprecated in favour of winver.h - I guess they finally removed it from vs2005. I've committed a fix to SVN.
Thanks for the report.
Regards, Dave.
