I thought BDS C on a Z-80 had ints as 8-bit rather than 16-bit?
I've never used BDS C so I can't say for sure.

For comparison purposes, a DEC-20 assembly program to do that takes 5.8
cpu seconds.  That's all in a register: (movei 1, =10000000; sojn 1, .)
When moving it to and from a memory location, it takes 15.9 cpu seconds.

The equivalent program in C with i as a long and with cc -O took 85.7
cpu seconds on a 11/70.  Pretty good performance by Lisa I'd say.
