Bit of a fanciful context given the original question. First you have to
"assume" the OP is talking about compiling, then you have to pull from
vanilla, and even then you need to *disable* the default in order to
later enable it - all to justify a convoluted answer to "Are there any
command line statement(s) that will enable the system to use more than 4
GB of RAM?"
10 points for creativity?

Perhaps because 64-bit gives their use case brings disadvantage but no
advantages? Perhaps for other reasons. To assume that you *should* use
64-bit in all cases is incorrect.
