c++.dos.16-bits - long long support in 16 bit memory models?

I know long long is currently not supported in 16bit memory models.
Why is that so?
Do you plan to include it in future versions?


I'm working on an embedded application that is using barcodes, and long long
support would make thing much simpler. Alternatively I know I can use some of
big-int libraries (or do my own code) but they are slow and take a lot of in
the final executable, and in embedded enviroment each byte counts...

I also would like to request such a feature. In my case, I am working with logical disk sectors, the 64-bit memory addresses returned by INT 15H/E820H calls, and I'm using the Pentium TSC register for timing.
