How can you have skew? That is the whole idea of benchmark is to
compare
two machines. I would expect that the simple C that was given would be a
good test
when judged with other benchmarks. The 8080/Z80/8086 all generate the
same poor
code. This surprised me as shows how poor the 16 bit intel product was.
The PDP-11
version was rather nice but it even has a few quirks.

PS. Note all my FPGA machines generate nice 'Small C' code and have a
resonably orthogonal instruction set. The well hacked Small C compiler
self compiles under
24 KB. A similar compiler for the 8080 is about 48KB.
