mcdb_make.c - clarify comment and key limit in 32-bit.  In practice, having the mmap fit in 4 GB address space, the size of data and overhead of each mcdb record (currently 40 bytes as I write this) will limit the number of keys to less than 256 million, so the code does not actually impose additional limits beyond the restriction that everything fit in 4 GB for 32-bit processes.
