Yes. We are using a unsigned long for the size. I consider switching to
64bit values but I did not do that till now. There is no check for
overflows which is an other porblem. Btw. DJB does not offer a 64bit
version of scan_ulong() -- this is one of the reasons that make a switch
to 64bit values complicated.

At the moment it is the best to disable the size restriction on so large
maildirs and use only a file limit.
