auto build r3347: 2 of 7 builds failed - 4 regression tests failed

Hello

I could use some pointers as to how to debug error messages like these:

Appearantly my code does not compile on "ming32", which I guess is the 
Windows-port of the application?!

My major issue with the compilation errors is that the supposedly 
missing function CacheItem::CacheItem() is never used on any of the 
lines mentioned in the error messages. The lines in question (line 27, 
29 and 31) contain (almost) empty constructors for DirectorySetItem().

I guess the problem somehow relates to that DirectorySetItem inherits 
from CacheItem, but in what way would this be the source of the problem? 
CacheItem is defined/declared in libmutil, and that library compiles 
just fine.

Does anyone have an idea about why this error occurs?
