You can insert an explicit cast to unsigned int if you really need to
remove the warning. If an int is defined as 32 bit in your 64 bit
system you are safe as long as you keep number of children for one
group node less than 4 194 304..
The alternative would of course be to change the return type of
Group::getNumChildren to vector::size_type which I believe is defined
as size_t and is probably a 64 bit long long integer but I am quite
sure you will have many more warnings to remove if you try this.
