Where are int48 and int64

[Marnic]

Am I right that int48, int64 are not supported types for the 8 bit micros?
I just cannot see the reason for leaving these types undefined given the high
speeds now attained by the 8 bit Microchip families.

No, they are only supported on the 16bit micros.
You can use a typedef to create these as an array of bytes or int16's,
but you then have to write your own arithmetic for these. I've done this
in the past for an int24, and int30 type.
On the original 8bit micros, it made sense, since the maths is very bulky.
However on the newer chips with a lot more ROM, and often hardware
mul and div, the libraries can be a lot smaller. Perhaps suggest to CCS
that it might be useful to offer an option to support these.

It should be possible to take Microchip Assembler versions of the math and 'wrap it' or whatever is the real term.... to have a program run it as a 'function'.
