This is incorrect. The V20 has an 8080 mode, not a Z-80 mode. 

There are also various software support packages to complete the CP/M
environment by making use of the V-20 processor under the MS-DOS system.
I have heard of public domain ones, but not used them. I use one
put out by Intersecting Concepts called Acceler8/16 (not public
domain). I then run M-80/L-80, DDT, etc. under that. I haven't yet
tried BDS-C, but I think it should work.

Acceler8/16 also includes a software simulator of the 8080, so you
can do the same thing without an NEC V-20 processor. This works
fine, too, but is of course a lot slower.

You can also get MS-DOS cross compilers that produce 8080 or real Z-80
code. I know Aztec makes (or made) one. I've seen it but I don't
have it myself.
