I do know of a great start.  Most of what is needed is here:
ftp://gatling.ikk.sztaki.hu/pub/z80/

It compiles OK, but needs some work (e.g. current default address is 0000h as it's intended for embedded ROM use and not CP/M and the like.  If this code can be made to work reliably with George's zmac, and I know of no reason why it can't, all cross development could be done for embedded boards, CP/M, TRSDOS and all its derivatives, and probably even MSX as both Macro-80 and Link-80 exist for that platform.  Memory limitations for Z-80 development purposes would cease to be an issue as long as the resulting code used overlays or fit in 64KB.

I have exchanged emails with the original author and he hasn't looked at the code in many years and he basically said "you're on your own, modify it any way you want".  However, it's known to be essentially functional correctly handling several hundred symbols, I think it just needs a bit of TLC to make it work for CP/M, TRSDOS or wherever by default.  It will successfully search Microsoft high level language libraries, Aztec C libraries and anything else in *.rel format.

Free of the memory limitations of a Z-80 at both assembly and link time, I think that should be plenty of mojo for Z-80 or 8080 development.  I've let it sit for a few months, but now that George has put zmac into the wild, I need to do the same for ld80 (lousy name - conflicts with Microsoft's ld80.com linker - maybe ld80x?).
