dcdbquery not compiling

dcdb (more precise: dcdbquery) is currently not compiling for me (using 'make all' on master-branch): Multiple errors of:

query.cpp:108:31: error: call of overloaded ‘TimeStamp(long long unsigned int)’ is ambiguous DCDB::TimeStamp prevT(0llu);

Changing 0llu to static_cast<uint_64t>(0) solves the compile errors but reveals linker errors, e.g.:

/LRZ/dcdb/dcdb/tools/dcdbquery/query.cpp:142: undefined reference to `DCDB::delta(unsigned long, unsigned long, long*)' (abbreviated)
